"Payment not recieved" sms

After so much patience with the notifications from IncredibleConnection, I have decided to write this message.

It is with great disgust that after every payment each month, I receive an sms which tells me that you haven't received my payment for the month, and this has been happening every month.

I have now received an sms informing me of the payment that hasn't been received, since when are you deducting my account on the 14th or the 15th. Ref***)

The contract that I signed with you has an agreement at the end of the month, if there are changes I need to be in agreement with that.

Now you are threatening me of the arrears, whereas my account is up to date.

How can i have arrears when my debit date is still far? WHY?
