Standard bank extremely poor credit card service

I paid up my Standard bank credit card end of February and wanted close my credit card account which was on a Friday. I went into the Cape Gate branch and was told to wait as the money I paid in was not reflecting yet (which was strange as it was paid from my Standard bank current account into my credit card...). I went back again on Tuesday 4 March to Cape Gate Standard Bank and asked to see someone. This person only put me through on the phone to the credit card department as she could not assist me with it. I spoke to a man first who again transferred me to someone else, a woman. I informed this person that I paid in the amount into my credit card account that I borrowed AND that the bank had already taken off the monthly installment, so my credit card account is in credit. I informed her that I would like my credit card account closed, refunded the installment the bank already took off, the credit card tile on my Standard bank banking app must be taken off AND I want proof that my credit card account has been closed, emailed to me. Today is now Sunday 9 March and the only that has happened is ALL the money was taken out of my credit card account, I have received NO refund of my own money, I have received no proof that my credit card account has been closed and the credit card tile is still showing on my standard bank banking app. I call that poor service...
