Where is my payback that were promised to me by Vodacom?????????

Due to Vodacoms useless online up grading system I have been tying sins 28 March 2021 to resolve the problem. Out of box fault. It took vodacom a month to collect the phone. Promise upon promise were made. Eventually I were promised a payback for the two devices that I had to pay for one faulty and an upgrade on a handset that were not due for an upgrade but were upgraded anyway. The payback were promised to me on 4 May 2021. I would recieve it after 7 to 14 working days. We're contacted on 19 May 2021 to tell me the payback has been approved and I will recieve it in 4-5 working days. Guess what to my surprise I have not recieved a sent. Not a call. No answer on my e mail sent, sweet blow all. Vodacom has the worst after sales service. No sorry no after sales service. And yes tomorrow I will get a reply stating a vodacom agent will contact you shortly. I have not had a phone for 2 moths due to Vodacoms lack of service. I have to borrow a phone. Your Service Request *** is now being processed by Gloria Sehenye who will be in contact with you shortly. I am still waiting Gloria!!!!!!!!! Where is my money?????????? And I a almost sure both hand sets will be decucted off of my bank account again because even after a cancelation done by Vodacom both the handsets appear on my account.
