Pathetic service

I requested are repair quote for my cell-phone from The Lab Illanga Mall, Nelspruit. They firstly refused assistance until I paid for the quote, which I then did. I had to phone a few times to enquire about the quote before I actually received it I was then told that I had to pay a 50% deposit, then only will the part be ordered. The part will be available within 4 days after I pay the deporit. I paid the deposit on 01.03.2021 and heard nothing from them. I phoned on 16.03.2021 and then I was told that the part has arrived. I made an appointment for the repair for 22.03.2021, as I explained that I cannot hand it in any other time, as I do the banking for three businesses and need my phone for that. It was confirmed that they will be able to do it today. This morning, I drove to The Lab especially for the phone repair. When I arrived there I was told that they will not be able to assist, as the technician is off today. When I asked to speak to the manager, I was told that he is the technician that is supposed to assist. I then asked for my deposit money back and again, I was told they cannot refund me as they have no cash and no access to the bank account. This is absolutely ridiculous, I waited almost two months now and still my phone has not been repaired! Pathetic service!!
