Bad service waiting 5 weeks!!!!!

Gave my iphone6 in for the screen, video audio and mute button to be fixed. My phone is insured. I went to Vodacom Mall@Reds branch on 11 Jan and requested it to be fix. Completed the document incl the insurance papers and off the phone went...received sms on 15 Jan to accept quote R3417-47 from repairs in Potchefstroom just to realise that they never sent the insurance papers to repairs. Phoned repairs and asked them to talk to Vodacom Reds as I completed insurance papers. Heard nothing and on 21 Jan phone was ready for collection. (2weeks)NOT FIXED AT ALL!Send in again on 29 Jan with insurance papers again!!! Sms received to collect on 5 Feb and (4weeks)NOT FIXED AGAIN!This time the find my iphone app was not deactivated. How must i know that it must be deactivated. Isnt it their job to inform me to deactivate? Why does it take 2WEEKS every time to inform me? send off again on 5 Feb for repairs! Phoned on 12 Feb to get an update- response: waiting for insurance to accept the quote?! After 5 weeks and youre stil waiting for the insurance. Now on 15 Feb get sms in for repairs and waiting for part! REALLY WORST SERVICE EVER! I have 3 phones on this contract and cost me R2900 p/m
