FNB credit card ***** - unresolved.

My credit card was ****med two weeks ago. Credit card account number: ***20 4009. The day before the ****, I contacted their call centre 3 times as I received a SMS saying "possible *****". The calls were recorded and not successful - relayed, cut off etc. Then the Friday, I afternoon I received a sms saying my card was used in the northern suburbs, though I was in Stellenbosch and my card with me. I stopped the card on the app and contacted FNB. I spoke to Josephine, who said that it will be sorted out. Rr*** is the reference number. I have not received any communication from FNB again, though I received a new card. There was in excess of R5000's purchases made on my card. These were made in the Northern suburbs - between 30- 50km from where I was. I had the card in my possession. The amount of money de*****ed has not been repaid into my account and it is acrruing interest every day. Please help me sort this out.
