Pathetic Customer service from Telkom Kolonnade

I am disgusted and still in awe of one of the worst experiences evr received from a service provider. My IPhone 5s required repairs. My phone was booked in, but returned in 3 weekd unrepaired becoz find my iphone was switched on. i switched it off and returned it to the store who said they were unable to rebook it in for repairs. after my countless calls with the call center i had to go to the store myself, call the call center, and get a lady explain to the Telkom employee how to rebook the phone in.The Telkom employee assured me that she understood what to do and she would book the phone in on that Monday. 2 months have passed and i haven't heard a word about my phone, the call center agents tracked that my phone is sitting at the courier company, so i waited for feedback. However, this weekend i decided to visit the Telkom store in Kollonade, only to find that my phone has been sitting there all this while, without even booking the second repair. I asked the Manager how can he not inform me or atleast check that a phone is sitting in his store for 3 months and he could not reply. I am disgusted, such poor service. i want to cancel my contract immediately!!!!
