POOR SERVICE ON REPAIRS

I am totally disgusted in writing this report but I am left with no choice I handed in my brand new Samsung S6 edge phone for an OBF , it is now a week later and there is no response , I spoke with Tebogo and his manageress and I am told that they awaiting feedback from Mmbatho branch , I find this totally unacceptable I am a Vodacom customer for 16 years and I do not appreciate this at all, I WANT MY PHONE BACK IMMEDIATELY OR CANCEL all my contracts with Vodacom and I will go to another service provider who is phoning me all the time to switch over!!! CAN SOMEONE WITH AUTHORITY PLEASE ASSIST AS THE STAFF IN FORREST HILL CANNOT ASSIST AS THEY WAITING FOR MMABATHO TO AUTHORIZE EXCHANGE!!! YOU CAN REACH ME ON MY PRE PAID CELL NO ***..
