Terrible Service from Repair Center

I have booked in a phone on the 07/08/19 at the repair center in Durban Town, I then picked up the phone on the 13/08/19 & it was still not fixed. I took the phone & was told the part for the phone will be ordered & delivered within the next two days & will phone can be dropped off in the morning & picked up in the afternoon. I followed up with the technician on the two weeks ago & was told there was no available part in SA for the phone & it was ordered from overseas so it could be sitting in customs. I called the technician today & was told the part will be here by the end of the week but if not they will send the phone to Jhb. How can a service provider this big not be able to sort out one simple repair on one phone. Giving your customers the run around is something Vodacom does best but double debiting us or debiting us on the wrong day is something Vodacom could care less about. Please can someone fix my phone as I need it for work purposes.
