Worst bank ever

Discovery just lost a loyal client I had a discovery credit card for more than 10yearrs now . Last year September I was lured to open a bank account of which I did , little did I know the worst to come , I transferred my savings to it and hardly use it and I transferred R500 every month . Come January I went to buy something for R1500 then my account was blocked . After two weeks I try to withdraw R500 it declined and someone from ***** unit told me it was blocked then try to unblock it at the same time holding the phone for about 3hours waiting to for them to sort their mess, after a week again I try to purchase at pick n pay the card did not work , when called them “the problem is not their side” another two hours waiting to be sorted , wait another week to use the card , the problem again not working. IT IS NOT THEIR SIDE PROBLEM”all the time I was told . I then request to close the account as I can’t access my money when I need to use it , I was told someone will call me within 2working days ... it took 3weeks and I was so angry that someone called me and I just said I don’t want to hear stories just close it. I will stick to medical aid only. A terrible customer service
