Bad service from Vodacom Repairs Mega City

My phone (Samsung A31) suddenly went blank on the 26th July 2022 while I was using it. I took in at Vodacom Repairs Mega City (Mmabatho) the same day. I received a job number (***1) & was told I will be given a call after assessment. I was then told that they the insurance needed an access of R343 to fix my phone (mother board & screen needed to be replaced). I never received any updates since then & had to call the shop every week for a new update, of which I was told that they were still waiting for the insurance to approve. I decided to go to the shop yesterday (15.08.2022) & I was told that the fitted parts were not working & they needed a cancellation so that they could requote again. I was promised that I was going to be called today for an update but that has not happened. It has been 21 bad days for me & I am now thinking of terminating my contract with them because of this bad service
