Poor Service All Round

I took my apple iphone 6 in for repairs early January. The phone had been issued by my insurance as a replacement handset for a previous faulty handset. The phone is still under Warranty. The phone proceeded to sit in the autopage shop for 3 weeks. No progress what so ever. I had to phone in and basically make sure they were doing their job. Eventually after 3 weeks it was taken to a repair centre. Now no matter where i phone no one can give me a progress report on this phone. Autopage Call Centre says that they are awaiting quote conformation. Miro is saying that they are awaiting approval and the insurance is saying its not their issue as the phone is under warrenty. No one is able to give me feedback as to why there is such a delay and when i will be getting my phone back. <br> <br> This phone is under warrenty for goodness sake. <br> All i ask is that my phone is repaired and given back to me. Your customer service is appalling. How can a warrenty repair be so complicated?
