Poor Service from Vodacom Repairs Center

Got a new contract with Vodacom. After 6 weeks the new phone's screen starts Glitching. I take it to the Vodacom repair shop in Vanderbijlpark on 11 July 2020. Receive a job receipt and job number *** and was informed it will take between 7 and 14 work days. On the 27th of July after hearing nothing from Vodacom I call their Repair center only to be informed that they only received the phone on the 22nd of July. When I asked what happend from the 11 - 22 July the answer was "I dont know"! Now I have to wait again for 14 working days from the 22nd. And guess what? I still have to pay them for a phone and a service I do not have? Absolutely pathetic service!!
