Worse service and experience

I'm an Vodacom customer since 2000 however the last 6 year I'm been having more trouble with Vodacom and the Rewards contact center that ever in my life. Never was upgrading your contract as difficult as now. I have 11 lines and pay +- R3500 to R3800 per month on my contracts and its impossible to get the contracts correct, for example to only renew a line for the next 24 months 10G data on an line that I pay R149.01 currently, no device, nothing change only new contract term, you will think that what will go wrong. Now let met tell you you will end up paying nearly R200 for this contract as all unnecessary services that was not requested been added. And then please do not try and cancel the contract in the 14 day cool off time as you will loose all our data that was on the phone before the upgrade, amount due to Vodacom will not be correct as per previous invoice before upgrade and your end date of the contract will be a total new date. The best is that no one can give you answers, correct your bill and sort out the mess. Rather you will be ask to phone this department or that department, no one taking responsibility or ownership of the problem. No after being on the phone from 28 September 2021 till today trying to sort out my contract still no joy. Now please understand me, should my account not be sorted out still in this week and an responsible consultant with integrity phone me I will take this matter further and please note that no debit orders will go through my banking account I will make sure of that. The user that done the upgrades was EL_MADAA002 on the 28 September 2021, please listen to the recording on our conversation from +- 14H00 till 16H33. I was also unable to log an formal complaint on the 2nd October when I have spoken to Denio Masinio at after care service and Pumla Netlapo manage to put my call on hold wile I was speaking to her and explaining my problem on Saturday at 9H58, that was very unprofessional and only after I lost my cool did she try to apologize and that with an attitude. This was the worst experience that I had with Vodacom. Sadly this is also not the first time that this happened.
