POOR SERVICE / ANSWERS ON REPAIRS

Gave in my phone for repairs on 12 October 2018 and made the payment....... On Friday the 16th of November I phoned the repair centre and they said I can expect my phone to be delivered to MTN Rosebank on Monday morning the 19th of November, I also asked if I can collect my phone myself and they said no we are not allowed to collect our own devices from the repair centre anymore we have to wait for the devices to go back to the branch where it was booked in....... I phoned MTN Rosebank Monday afternoon and they told me the phone is still not delivered, I phoned the repair centre again where they told me sorry still waiting for the device to be dispatched and that will only now be tomorrow the 20th of November, I phoned MTN Rosebank today and told me they still haven't received anything from the repair centre, when I phoned the repair centre again today they said that there is a backlog and now they can't tell me when I can expect my phone, give clients a proper answer and don't repeat yourselves with tomorrow, tomorrow..........
