RCS pick pay store card facility, company is inadequate

I have a pick n pay store account. I paid my monthly payment due on the 2nd of april. On the 10th i checked that my account was loaded with the payment, it was not.

I phoned the call centre and explained to them the situation about the payment. They double checked and said they cant find payment. They asked me to send the proof of payment to their email ***. I did that just after the call.

On the 13th today i received an email that i payed the amount into the wrong account and need to visit a Pick n Pay store for them to transfer the money into the credit card account.

But this is not a credit card account it is a STORE card account. I have used the same account number EVERY month. With the same reference every month and never has this been a problem or i had to use another account.

Seems this department is not adequate to help customers. I want this fixed immediately. I will not go an transfer the money into another account which is not the right account
