Tired of waiting for Vodacom Repairs

I have taken my phone for repairs at Vodacom repairs shop at Eastgate on the 5th of February 2022. I was given the invoice and I opted to pay for the repairs immediately. Now it has been over 25 days since I have been waiting for my phone to come back. What annoys me more is that I was told it will take 7-14 days for it to be fixed. Since I took the phone in, no one has called me from the repair shop to update me on the progress. I have been going to and from to Eastgate to enquire about the status of my phone and I am told different things. On Wednesday the 2nd of March 2022, i went again and Laurel said she will give me feedback before the close of business on the 2nd of March 2022. Till today no cally, no feedback, nothing. What is going on? I use my phone for business I am doing and it's really affecting me big time as I thought by now it would have been sorted out. What must I do?
