LACK OF CUSTOMER SERVICE

On the 18th of October 2015 I went to Edgars with my younger sister to report that her phone was not working. Sboniso from Edgars took the phone for repairs and he said , repairs took 3 to 4 weeks. On the 11th and 18th of November 2015 my sister went to Edgars to check her Phone she did not get it. She was told by Sboniso that her phone is not yet back it was sent to MTN for repairs and MTN has courier problems. Sboniso mentioned all this without check on the computer or any register. Sboniso then gave my sister MTN number so that she can trace her phone. On the 20th November 2015 I phoned MTN gave them the IMEI number and they check on their system there was nothing from Egdars which was sent for the IMEI I gave them. I was then instructed by MTN to get the collection number from Edgars. Same Day I then contacted manager Khulani who is very rude. He told me that he will check the status of the phone and come back to me and he did not. Today he is saying the phone was with edcon contact center for 36 day. It went to MNT today. I just checked with MTN still nothing. I am failing to understand why the phone was with Edcon for 36days. on Friday was told they cant find it anywhere.
