FNB- How can we destroy you?

I wish there was a score less than 1 star.... In September 2019 I contacted FNB telephonically to enquire about opening a Credit Card with them. The lady on the phone was friendly and helpful and i thought that all was well. She offered me a cheque account as well which, after discussing the benefits with her, i decided to do. My Cards arrived rather timeously and all seemed well. A few weeks later my internet banking stopped working. I called into the call centre and was told it was a fault on their side and they'd fix it timeously, which they did. This lasted for a week and then it stopped working again. When i called them again, they asked for my ID number for verification. I was then informed that due to an error on their part, my ID number was linked to a Barbara Morgan, instead of myself, Bronwyn Morgan. I was told to go into my nearest branch with my ID to have it remedied. I did this at the beginning of December. After spending 2,5 hours in the East Rand Mall branch, I was told that they had no idea how to fix the problem. They were unable to verify me using their system as my fingerprints do not match what they have on their system as their system now links my ID number to this other woman. So although I am sitting in front of them with my ID card, they cannot verify who I am. I was told that they would escalate the problem and that someone would be in contact with me shortly. And I am still waiting. My husband and I are in the process of wanting to buy a house and now my ITC is stuffed because my name and ID number are linked to a stranger and it looks **********. I can't use my internet banking and have to do all EFTs at an ATM, I can't extend or change my credit limit or do anything other than swipe my cards. Many people tried to warn me about banking with FNB and boy how I wish I'd listened.
