Disgusting service from Vodacom

In september 2020 i requested to have my contract changed to pay as you go. Pumeza the call agent offered me a contract at R39 per month, which i confirmed a couple of times to ensure its only R39 and she assured me it was, I was then upgraded to a huge voice bundle contract in which I did not agree to. I have called countless times to have this changed and each time they tell me its fixed but its not, i cancelled the debit order as i refuse to pay for something i did not ask for, and they now say I owe over R4000. Ontop of that they have suspended my number and i am without a phone. I went into a store to try fix it on Friday the 19th of February 2021 and the store manager sent an email requesting they fix it. The only thing I have received from Vodacom is another sms telling me i owe them over R4000. Ive had enough of this useless company I want my number on pay as you go so i can port it to another cell phone provider. Ive been a loyal client with vodacom for so many years and to get treated like trash!!
