Poor service

In June of this year (2019) I, Mr I Bulbulia was credited on my account 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 tge matter was resolved. However, sadly to my dismay and disappointment this auto refill data bundle is still active and Vodacom has billed me over R1000 for this service 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, 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.
