A NOS deixa-nos cansados

Bom dia, eu queria comprar um cartão eSIM da NOS e fui à loja em Lagos, Algarve, mas disseram-me que o cartão não estava disponível na loja no momento. Fui lá cinco vezes em dois meses! Sempre a mesma coisa. Perguntei como poderia encomendá-la pela Internet e deram-me o número de atendimento 16990. Marquei uma chamada telefónica para as 11h da manhã do dia seguinte. Liguei e o telefone tocou durante muito tempo até que alguém atendeu. Explicaram-me que eu deveria ir a uma loja e comprar o cartão lá... Eu disse que já tinha ido lá cinco vezes em Lagos... Então, fui transferido para outra funcionária, que também foi simpática e competente. Ela explicou-me que o cartão E sim é apenas para clientes da NOS... Foi a primeira vez que ouvi isso...! Ela disse que eu deveria ir a uma loja da NOS e comprar um cartão SIM «normal» e, em seguida, trocar o cartão SIM por um cartão eSIM. Oh meu Deus... Que complicado e «amigável ao cliente»... Good day, I wanted to get an eSIM card from NOS and went to the shop in Lagos, Algarve, but was told that the card was not currently available in the shop. I went there five times over a period of two months, and it was always the same story. I asked how I could order it online and was given the service number 16990. I arranged a phone call for 11 a.m. the next day. I received a call, but it rang for a very long time before someone answered. I was then told that I should go to a shop and get the card there. I said that I had been there in Lagos five times. I was then transferred to another employee who was also friendly and competent. She explained to me that the e-SIM card is only for NOS customers. That was the first time I had heard that. She said I should go to an NOS shop and buy a ‘normal’ SIM card, then exchange the SIM card for an eSIM card. Oh my God... How complicated and ‘customer-friendly’!

Impossible to communicate in English…

Impossible to communicate in English with them via phone or app. There App is about as bad as can be....all it wants is to sell you more . Customer service is zero . My internet service drops to year 1999 if there is festa nearby. The router gets so hot I'm worried it will set fire to my house Definate evidence of chocking, illegal in Europe.All devices defaulting to 144 megs , not even 250;megs on YT so have to manually switch to 250 so I can see reasonable video quality.

Absolute scammers

Absolute scammers, was signed up to a long-term contract without being told. Then they WILL NOT let you cancel the contract - I haven't even been able to use the service as the SIM card is locked and the PUK entry code they gave me is incorrect. Everytime I call I get put on hold for about an hour and nothing is resolved. STAY AWAY.

It comes with an internet package

It comes with an internet package, but they charge one price and then change it to another absurd and terrible price; the service is awful.

The worst e-commerce platform that i've…

The worst e-commerce platform that i've used for a long time, that i remember of. Unbelievably inefficient platform. I tried to buy one mobile phone for more than 6 times now. The customer service is ridiculously difficult to get. The agent keeps validating my mobile number and finds nothing just because it's attached to enterprise service. Still, does nothing else, does not redirect to any agent. Had to actually select that i wanted to subscribe a new service and then get redirected through various teams until i gave up. In the website, after reaching the final purchase confirmation, with all payment details accurate, it simply continues, i receive an email, an SMS, with the confirmation of the order. But then, it's cancelled twice. One of them it states that it's awaiting payment with a order track link. The link simply does not work. It states you can know more details on your account but that menu is inexistent. So, no details can be consulted and if the order remains in this status it cannot be paid because there are not details. This seems mind-blowing puzzle. Unbelievable. If i handn't a voucher to buy a mobile phone at this store i would have gave up such a long time ago. Never seen something like this. Tried to be patient but it has limits. Honestly don't understand how this companies still keep on the top of communication companies, at least in Portugal, with this kind of inefficient platforms and customer service.
