MAJOR PROBLEMS WITH CONTRACT PHONE REPAIRS/SERVICE

From the BEGINNING off all this repairing problems i was referred by Marileth Jansen Manager of MTN Kolonade to repair my phone inside Dion Wired Samsung shop for the first time.THE QUESTION IS Why dont MTN Kolonade repair the phone?My Note III is not even a year old it went in for 4 repairs. It is totally unacceptable I am paying a contract for a BROKEN phone.In the beginning of January 2015 my phone broke again 3rd time I took the phone to Samsung Brooklyn Mall, the manager Can said to me they cant replace or book the phone in again, I must take it back to MTN.Then I took it to MTN Kolonade and they did book it in not asking for S pen.Johan from MTN phoned me a day after I booked the phone in asked me for my phones S PenThey are not able to book the phone in without a S Pen.I took the pen in.On 22 Jan 15 I did get my phone back from MTN still not working.Marileth told me they did repair it No report stating the problem.I took the<br> phone in to MTN Allandale rd Job card ALWIC***(4th repair) we realized my phones S Pen was replaced at MTN with dummy S Pen.Almost 3 weeks know no feedback from MTN<br> Ref no for the 2 repairs with Samsung ***, ***
