Vodacom becoming common *******

In June last year (2019) I, Mr I Bulbulia was credited on my account I***8 for an amount claimed to be owing, due to an auto top up bundle been set on 1 of my lines *** number without my consent, upon querying this amount, the consultant advised and reassured me, that the auto refill data bundle 500mb had been cancelled on the line, and that in future there would be no further charges for it as the matter was resolved. However, sadly to my dismay and disappointment this auto refill data bundle is still active and Vodacom has billed me over R1500 for this service to date which was advisably queried and supposedly cancelled in June of this year. My account is now sitting with the collections office due to the lack of quality of service received thus far, after various and numerous attempts have been made to rectify this matter, however, as explained the quality of service on Vodacoms part is poorly lacking, I've tried contacting *** and the consultants keep on cutting my call, the consultant this morning was even more inventive, he cut my call as I started explaining and than he called back and let it ring once and cut the call, probably to show management that he tried calling back. Kindly assist to resolve this issue promptly as a product consumer I would like that in future I would be able to rate your service better.
