Very poor service

I received a call from their call cent Dr offering me savings card. I gladly accepted it. When courier called and advising about the delivery, I realised that they called me with my ****en surname. I advised them that I don't use that surname anymore and buy then I was waiting for home affairs todeclare me divorced. They advised that they will escalate this matter to Feb. I waited for more than a week to get feedback until I called Fnb. Then I had to be tranfered to I don't know how many department. At some point the calls were dropped. Eventually I spoke to a lady over a week ago who advised that I need to send my docs so that my info can be updated and k must not be charge for that. I'm still waiting for the feedback. I am still waiting for the card. It's over a month since I received the first call. I wonder if I made a right decision to join Fnb if I get such service. I want to cancel this card. My contact is ********** 843. REF: ********** 0_ ********** 26
