MTN is a waist of my time, no customer service or care

seems like MTN don't really care for their customers.

I logged a repair claim with MTN Insurance on the 4 December 2019 waited for MTN and for response, on the 14th they asked for the axcess amount of r150, paid this on the same day and sent to them the pop. sent them the collection address also on the same day and they confirmed that they found it on the system. now from here I kept on having to call MTN for pickup dates with different promises from each different call operator. the phone was then only picked up on the 10Jan with excuses that shipping co's where closed... On the 13th Jan 2020 was told that the device would be assessed by the repair team the next day... now after this is have been getting mixed responses from the call centre agents and again I have to be the one following up regarding the progress of the repair.

now on the 21st was sent an email that the device is in Quality control and will be sent out to me Wednesday or Thursday, (this didn't happen) I had to call again and was told they will definitely deliver it Friday before 5pm,(also didn't happen) I called again and was promised it will be delivered at my home address Saturday(well no surprise, this also didn't happen) Now Monday the 27th I get totally different answers, now apparently the device has not been repaired as the quote has not been accepted by some MTN person, so MTN has been lying to me about the delivery?

so how does thigs work at this emptyN, full of empty promises to try keep customers?
