Absa Appalling customer service

I am really disappointed with Absa. I have made a payment from a FNB account to my Absa credit card. By mistake i put the card number in the 'MY REF' field instead of 'Recipient REF' field. After a few days when the funds were not reflecting i realised my error and immediately contacted Absa. I was asked to send the details and proof of payment to *** which i did over 2 weeks ago. Since than i called in multiple times and sent multiple emails, yet no joy or response from Absa, not even a reference number. Yet absa sends me message that i am in arrears with my credit card. Such service from a financial institution is just appalling.
