BILLING AFTER CONTRACT ENDED

I had a 2yr data contract with Vodacom from 2017, and it ended in 2019 April. I walked into the Sunnyside store (Pretoria) where I contacted, and asked that I want to be released from it, as it was due to end in April 2019.

They gave me a four digit number to call for cancellations - this number is never answered! on the umpteenth call when it was eventually answered, the response was that they will cancel and de-activate the account.

They continued to bill me and I sent an email (12 April 2019) asking them to stop. the billing has continued throughout 2019 and no matter how many any times i called and wrote emails to cancel, my bank account continued to be deducted. I then resorted to reversing the deducted money every second or third month Vodacom is holding me to ransom - they have now set their lawyers to me, and I am NOT USING their data!! There is no name or face to deal with when the contract ends. Yet when you contract there is a store to walk into
