Exhausted bad service

I have paid my Vodacom account at Vodacom Shop in brooklyn mall on the beginning of July 2018. Vodacom phone me to inform me that my account is in arrears of R328 more or less. I paid my new installment plus the arrar amount. Up to now Vodacom is still phoning and sms me regarding my outstanding payment. I phoned vodacom to inform them that i have made payment and they told me that it does not reflect on they system. I then emailed Vodacom the proof of payment. Still i receive phone calls form them. I then in frustration phone Vodacom and they let me email the proof of payment to a supervisor. STIL I RECEIVING PHONE CALLS FORM THEM REGARDING MY ACCOUNT!!!!!!!!!!! I am fedup with Vodacom. Ontop of this my portofolio has drop down from a P0700 down P0600. THIS NEEDS TO GO BACK TO WHAT IT WAS. THIS IS NOT MY PROBLEM THAT VODACOM IS ***********. I have to pay for vodacom mistake. If my account gets locked and it does not get resolved i will make sure that every social network will find out about the bad **** service i received from Vodacom.

My cell number is ********** 981
