Vodacom Billing

Spoke to a consultant on the 14th of September with regards to an additional number I am being billed for. She confirmed that it shows on the system that I requested cancellation November 2021. To date no response from Vodacom so I decided to phone them again. Spoke to a lady in the cancellations department, said that she can't pick up any correspondence (funny enough the previous consultant gave me the date yet it doesn't show today). Told her that she must ensure that this number is cancelled and then she blames me of threatening her. Vodacom you need to look at your level of service! Quick to debit an account yet no so quick to respond / resolve a query!
