No interment connection. I want my refund !

Vodacom is the worst. I did not have internet connection to my router for 3 month but I will still paying for my contract. When I called the told my some lie story about my area being impacted by coverage issue. Which is absurd for 3 months ??? And when I called to cancel my cancel they still took payment from my account. For what ? They didn’t Render me any services contracted ended in August but they took a debit order in September even thou I cancelled. Diabolical and do even bother emailing that talktous complaint email they never respond. Even when I called they said they logged my and I will get a reference. I was never given any reference no phone call from them. I want my refund you ****mers !!!!! I will be writing to ombudsman because they have failed to deal with my query for months now they just do not care hence I did not renew my contract with them.
