Vodacom reluctant to cancel my data account

I’m not one who likes to continually complain but it is now at a stage where I am so frustrated with Vodacom They have been giving me the run-a-round since November 2020 I phoned Vodacom in November 2020 to cancel my data line as it was at the end of the contract and no longer required. I was assured that it would be canceled by the end of November. But I must also admit that I ran into problems due to covert during December and January So in February I get an account for R1989 but according to my calculations it should only be R1220 for two months for the mainline R610 per month so I queried the other R670 The consultant explained that the data line was never canceled and that because the contract had ended they no longer charge me R149 per month for the 10Gig data line they are now charging me R334 per month I was informed that they will file a dispute for the charge on the data line and the situation will be investigated and that the account will be credited. But that I should pay the R1220 on the mainline which I paid on the 15th Feb 21 There was no investigation done and no credit to my account so I phoned Vodacom both the accounts department and also the accounts collection department. The consultant I spoke to told me that there was no record of any cancelation or that I phoned in at any time. I was gobsmacked The consultant once again told me that they would elevate the query and they will investigate the matter and credit my account. I wasn’t about to take a chance again so I asked for a reference number 1 – *** I thought Thank goodness, that will now be sorted out but alas to no avail. My main line was again suspended on the 12 April 21 So this time I went into the Vodacom branch at Savannah Mall and a lady by the name of Sophia helped me for 3 straight hours we phoned the cancelations and then the accounts and then back to cancelations this happened quite a few times the accounts point the finger at cancelations saying that there is no cancelation on record, Cancelations Department says they can’t do anything, accounts must reconnect the line. I asked for another reference number for this call EL/TILLMOO1 as there doesn’t seem to be notes made of the call I make. Eventually, we got through to someone in accounts that said he can see all the inbound calls from me from November last year until today and it took less than 5 minutes and my line was fully operational again Sophia from Vodacom Savannah Mall really went the extra mile and I am really grateful for her help. She suggested that we wait until the end of April to see if there is an improvement on the investigation that they were supposed to conduct Well today the day after we spent 3 hours explaining the situation and expecting feedback on the investigation, I receive a further SMS saying that I need to pay R1336.95 to prevent my service from being suspended Well to me it is clear that there is something seriously wrong with the Vodacom systems. How can some see the notes on the client's profile and others can’t? It is also very clear that the one hand doesn’t know what the other one is doing At the end of one of the calls I rated the service 0 but nobody even bothered to phone back to inquire why I was so dissatisfied with the service. Why bother to have a rating if nobody follows up. Just a waste of time.
