complaint aganist vodacom

I'm not happy with Vodacom for *****ulently doing upgrade and not cancelling my contract and handing me over to the debt collectors. In September 2021 I cancelled my contract with Vodacom due to suspicion of ***** only to receive a call in 2022 that I owe Vodacom. I went to Springs mall Vodacom shop and I was advised to do an affidavit as the was an upgrade done of a Tablet and a cell phone, when I went back to the shop to submit the affidavit, I was then advised that my contract was not actually cancelled thus they handed it over and the Employee I spoke to was Mbongiseni who took the affidavit and said he was opening a case to be investigated and gave me the above reference number( *** )this was in September 2021 and until now the is still no progress. when i called the shop to speak to Mbongiseni he hung up the phone.

i wish i could get assistance as i am really struggling at ITC as i am listed there
