ITC RECORDS NOT UPDATED AND NO STATEMENT RECEIVED

I am very frustrated and not happy about VVM AND DIRECT AXIS NOT UPDATING MY ITC RECORDS WITH THE ANMOUNTS THAT IM PAYING. THEY DON’T EVEN RESPOND TO MY EMAILS/ I HAVE SEND A PROOF OF PAYMENT AND NEVER RECEIVED CONFIRMATION AND ALSO NO STATEMENT RECEIVED AS HOW MUCH IS MY BALANCE. I HAVE PAID R4000.00 ON THE 25TH OF JUNE. SEE PROOF OF PAYMENT. IT LOOKS LIKE I WILL PAY FOREVER BECAUSE THERE IS NO UPDATE AT ALL. IS THIS THE WAY TO TREAT YOUR CUSTOMERS?
