Annoyed customer... Foschini harrassing people for money if they are a day or 2 late

My account is due every month on the 1st. I did a payment on the 3rd and I received emails, calls and messages to advise my account is not up to date and I will b charged late penalties. This is a total *******... 3 to 4 days late and you get a late penalty charge.

I pay my account generally on the 1st, there are on the rare occasions my account is paid a day or to after the 1st, but is always paid in full and monthly total due.

Why is Foschini the only retailer harrassing people for money especially if the account up to date.
