Repairs and customer service

I have phone on contract and insurance which I pay month though Vodacom. In April I was in need of a screen replacement, so I took my phone in and paid about R600 excess. Please keep in mind that every time you take your phone for repairs they rip your gorilla glass off. Once I got my phone back from repairs, I immediate purchased a new gorilla glass (R250) and cover from Vodacom. A few days after repairs I noticed that my 3D touch was not working which I use often so it became an inconvenience. I took my phone back and clearly demonstrated to the tech guy that it wasn't working ever since I got it back. He said that I must send it back for them to fix. So I sent it back in and of course my glass protector gets ********** again. At this point I was annoyed as it was brand new and the fault wasn't even caused by me. I got my phone back and they then said that there was nothing wrong with the phone. The tech guy said that it must have been the screen protector that cause the problem with my touch and advised me to "bring it back" - what a joke right? They had already ripped it off and I didn't have my receipt on hand. That is as far as it went. That same night I was watching a video on my phone and realised how soft my speaker was - I didn't think anything of it was first until the next day I placed a new glass protector on (R200) I tried to make phone calls and could only hear the person on the phone if my phone was on loud speak. My ear speak was not working. I took it back to the get repaired and of course they now ******* another screen protector once again for a fault that was not caused by myself. Which brings us to current. I received a call from the repairs center to say that have replaced my speaker and that they are sending the phone back last Thursday (13/06/2019). I have phone my branch 3 times since then and have been told that 1) Delayed because of Youth Day, 2) I must wait for an SMS and 3) I will phone you back. I phoned the repairs center today and they said that you guys received my phone on the 14/06/2019. At this point, you guys have caused more than either inconveniences for me and I can't even received good customer service. Its also ridiculous how I must keep replacing screen protectors when I get my phone back from repairs with more faults than before.
