Vodacom PATHETIC!

In September 2023 we requested a quote from Vodacom for a premature cancellation. We received the quote and paid the FULL AMOUNT on the same day. I emailed the signed cancellation contract, proof of payment, id etc to them. They send me emails confirming the cancellation and also emails confirming the numbers would be converted to prepaid. Since then, nothing was cancelled. They keep on taking debit orders (without my authorisation) even today! We phoned the call centre numerous times, with the same answer: "We are sorry for the inconvenience, the mistake is on our side". Several promises of the correct department phoning us back.... still waiting for those calls. Eventually closing my business for a day to make a trip to Vodaworld in Midrand, AGAIN TO NO AVAIL. As always, they will call us back. Should I now revert to legal action against Vodacom? Since I did not authorise debit orders going off, which is *****. I have all the proof of payments, emails from Vodacom, etc. And still they are threatening us to suspend the prepaid service! This is the worst service from any company we have ever received. We are NEVER using Vodacom again. You are fast to issue contracts but when the contract is paid up - you start *****ing client's money with unauthorized debit orders and refuse to assist. PATHETIC!!!!!!!!!!!
