ANNOYED TO THE HIGHEST LEVEL BY VODACOM FIBRE

I am so ****ed off with how Vodacom is treating me .I have a fibre account with them and initially I changed my bank and informed them and they ddnt debit my account until my services were suspended.I then went to a vodacom shop in Woodmead to pay the outstanding amount and it was the 10th May 2021.Until date Vodacom keep suspending my services and claiming that they cannot see the payment?Isnt vodacom suppose to know what to do?or how to allocate their payment?Ive been going up and down,been to the vodacom shop twice but it seems as if somewhere somehow someone doesnt know their job?Please if I knew how to allocate payment I would have done it myself .THIS IS AN INCONVINIENCE TO ME AND MY KIDS AS THEY ARE STUDYING ONLINE ...FIX THIS VODACOM I EVEN WANT TO CANCEL THIS WHOLE THING
