Transfer

I recently changed banks to FNB hoping they are as innovative as they say they are, my 2nd month banking with FNB i transferred money to a closed credit card by mistake and I reported the matter on the 03rd of May via the chat option and the banker told me that this would take 3 days to be resolved, 3 days later I followed up and I was told 5 days, 5 days i followed up and I was told that due to lack of resources this will take 7-14 days and 15 days later I was told that this may take 21 days and after fighting with the banker's i was told to call the collections department of which i did and I've been sent from pillar to post every since. I really regret moving to FNB all i want now is my money and I am moving back to my previous bank
