UPDATE:
After absolutely zero progress on transferring the funds I decided to take a 800km trip to Poland to visit a Mbank Branch as I was told on numerous times that is what I should do to unblock the card.
In Poland the nice ladies in the branch said they cant do anything about the blocked card as they dont have access to the card system. So I called the customer rep to ask why they had told me to come to a branch to verify my ID if they still cant open the card. I was given a big load of bullshit with different excuses and in the end they said I should contact the person who sold me the card. They never even wanted to copy my ID even though I insisted so I wouldnt have to go back again.
This is such BS and they are obviously finding ways not to pay the customers back.
If anyone is planning a trip to Poland just for this I would advise you not waste your time and money as it still wont give any results.
Why didn't you call local police and reported a robbery?
They told you to contact the person that sold you the card? Weren't they selling all the cards in the first place?
This is a pathetic behavior from them. I'd expect this kind of thing in a 3rd world country. I'm very impressed it's happening in Poland.
Didn't you show them e-mails where they specifically ask people to visit a branch in Poland?
I dont know how their chain worked but I think they had resellers or smth. Yeah they told me to contact the person who I bought the cards from and ask him to fill a form to get the money transferred or smth. I really dont see how this is even relevant as I am their client with all the information about the card and not the reseller. I also told them countless times I will not be able to contact the person but they kept saying that "this would be best for the BANK and you" .
I was really frustrated and there was nothing I could do on the spot anymore. I will be searching some help from Polish legal forums and file a complaint to local consumer protection agencies. Its not even about the money anymore as sum locked up isnt huge. I just want justice - even if I have to pay more for it than I will get back.
