Cellphone booked in for screen damage

I booked in my iPhone for a screen damage and its insured by MTN on the 28th August 2015 , 2 weeks later went into the shop to check on it and apparently the agent who helped me didn't do it properly, Caswell helped me and I even emailed him a screenshot that I had deactivated find my iPhone, on the 6th October someone from insurance called me and insisted I didn't deactivate find my iPhone I gave them my log on details and it was apparently deactivated but still my phone is not repaired,<br> <br> I called the shop on Monday and Tuesday and spoke to Caswell he said he will trace it I am still waiting for my phone and come month end MTN deducting money for payments, all I want is my phone fixed cause I pay for insurance thereafter I am migrating to Cell C maybe they have better customer service, the said this its the second time I have a major issue and its only fixed after I complain on Hello peter.
