VODACOM: Contract not cancelled and billing continued despite numerous requests

My 2 year 'data' contract was due to end on 5 July 2021. I called Vodacom 3 times to remind them to cancel my contract (11 June, 12 July and 30 July) and on each of these occassions the operator said they could see that I had called on these dates, however, I received an sms stating "You will receive an SMS and email with your exact cancellation or conversion date. Until such time, your Vodacom contract cancellation is not confirmed". Needless to say my contract was NOT cancelled and I was again billed in July and again in August. I called again on 7 August to enquire why I was still being billed, the operator switched my contract to "pay as you go" and I received an SMS stating "Thank you for your patience and cooperation. Your query with ref number ... has been attended to. Proof of cancellation is required for credits. There is no cancellation or expired quoteon system. Thank you, Vodacom". What utter bull****!!! I want my money back and no excuses!! When I called customer services again to-day the call was cut off. BEWARE other customers. I would not advise you to use Vodacom services based on my poor experiences!!
