No phone for 5 weeks!

I accidental cracked my iphone screen.I called MTN they told me that if I had a spare phone that this process would be a lot quicker,if not I would have to wait 2 weeks so they could get a replacement phone.I told them that I had a phone I could use and they arranged picked up the broken phone.They informed me that I would get my phone back within 3 weeks longest.That was on the September 8th.On the September 28th an email requested payment for the excess,on the 29th payment was made with the MSISDN as reference which was incorrect,so the 30th ANOTHER payment was made and sent proof of payment.When called to find out the status,I was told there was no proof of payment,so ANOTHER proof of payment was sent.October 10th I called MTN,after several attempts I was given the repair call line.I spoke to the agent who informed me that not only has my phone NOT been repaired they still wait for a shipment of spares to arrive.I'm very disappointed with MTN's service I had to call every time to find out the status,not once did MTN try to contact me to explain why it is taking so long.I sent my phone in expecting it fixed within 3 weeks instead I've been sitting without my phone for 5 weeks!
