Poor to no service.

Hi

After many years of having a cell phone contract, I cancelled my Vodacom contract. On 02 May 2024 I contacted Vodacom to cancel my contract which was done. on 31 May 2024 I received an e mail from Vodacom that my number is now an pre paid number, and then I moved over to another service provider and I port my number. on 10 June 2024 I send an email to ***, requesting my refund of R910.13. on 13 June 2024 I received my EC-1TR6-20CNEH number on 13 June 2024. on 14 June 2024 a Cherity requested an bank confirmation letter, which I supp**** on 20 June 2024. On 24 June 2024 Cherity confirmed that my money will be paid back in 7 to 14 workings days subjected to approval. On 12 July 2024 I reminded Cherity that the 14 working days has passed, no response till 16 July 2024. Cherity confirmed that she will advise me when the refund will reach my account. I have spoken to 7 people at Vodacom since 18 July 2024 and 19 July 2024, no refund yet. I requested the e mail of the CEO, Mr Joosub Shameel, nobody want to assist me as I think then Vodacom will pay back my refund if Mr Shameel will intervene. Can anybody assist with contact detail of the big guns of Vodacom as I just want my money back.
