Debit card dispute

I’m not happy with FNB, I did a debit card dispute on the 19 of December 2022 and submitted the documents they asked for, on the 21st of December 2022 received an sms telling me to resubmit went toGateway branch to do that on the 30th got the same message again I went to the branch and did that and this Time I was told to wait for 10 to 30 days. Again on the 21st of January 2023 they sent another message to resubmit mind you I’m pregnant to be up and dealing with stress, I feel like they are playing my games with me. I cannot just live this R57,536,50 is a lot of money for FNB to do this to me, Need to pay may children’s tuition money please FNB do the right thing
