Poor level of service Part 2, I am Disgusted

once I was informed that Mtn is awaiting feedBack to find out which phone is insured, I was shocked. They had upgraded my phone to an iPhone 6 and they gave me the phone. Mtn has been billing me for insurance for an phone they don't even know is insured. It's strange becoz surely it should be my new upgraded phone and worse I told them I wanted my iPhone insured. What's even more shocking I was informed that Mtn did not bill me for insurance in feb , and I did not make any request to cancel my insurance. This is all so Frustrating, never did I think I could experience such bad service from a company like Mtn who prides it's self to deliver good service. I have never experience any issues when it came to claiming with Nashua mobile. At this point I wish they neverclosed down. reason for Mtn handling my upgrade was becoz Nashua mobile closed down. In the whole transition that took place last year, I informed them that I wanted to continue with insurance and that my iPhone must be insured, the lady who was assisting me said it was going to be insured and it will cost more vs what I was paying before with Nashua. I said no problem.
