Poor Service, blame game & lack of responsibility!

My Sony Xperia was damaged due to OBF, 13/01/2016 I left my phone at Cell C Musgrave in Dbn as it was insured. 05/02/2016 I got an sms to say I can come to fetch the phone, came back unrepaired cos the branch sent the phone to be repaired under warranty & not via insurance even though insurance docs completed & handed in to the manager at the branch. I've been following up from cell c repair centre to manufacturer repair centre weeks on end, then got sms saying phone ready for collection at the store. Got there see the phone had been quality checked, put the phone on & still doesn't work, it and seems like no-one bothered to look at it as an OBF. Unhappy I sent the phone back as prioritized, followed up on the phone again; had endless problems with insurance and cell c store. They came to the understanding that I was going to get a new phone as OBF. Days went by again eventually I get a call from cell c saying I can go to the store and pick up but I must now pay R1900 as per the store but C insurance says the store is lying. Called the store & head office they came to the understanding but I still haven't received my phone. I don't have a phone for 2mnths! Tired of being **** to!!
