Totally confused!!!

Hi, my credit card payment was suppose to go off on the 1st of April, but it didn't. I called customer service twice and visited the branch, they informed me because i was making regular manual payments on my card during the month, the amount was covered already. Today i got my new statement showing the balance of last month was brought forward.

So now i owe for last month and this month.

I called customer service again, they advised me not to make manual payments, as this confuses the system.

Not sure how me making payments regularly and standardbank getting their money is something bad.

Someone needs to call me and explain why i should not make manual payments if i have the money available to make the payments. Please dont make me cancel this card for something as stupid as this.

Regards
