Very very Shabby service from Vodacom (1month and counting)

I got a new contract from Vodacom with a Samsung S21 on the 27 Oct2021 on the 4 of November 2021 I had to return the phone as it had a battery problem. The Chatz Maville store did NOT replace the phone but send it in to Vodacom repairs. I contacted Thabo at CEO Vodacom for help. It is now the 26 of Nov 2021. My first bill on this new contract is now up for payment but I still have no Samsung S21. I have been sending Emails to Thabo but his last reply was on the 23Nov2021 after I placed a complaint on HelloPeter. And in that email he only requested the Job nr. I am now requesting my contract to be reversed so that I can apply for a new contract and maybe then get a working phone. This is very very shabby service Vodacom
