Incompetence to the max

I sent my phone in for repairs on the 17 July I received an sms saying they are sending my phone back unrepaired, I had to phone myself to find out what's going on, the lady tells me sorry the number provided does not have insurance, because I filled in another number belonging to the contract holder they did not pull up the correct contract, even though I was told numerous times by the customer care agent I need to put that number as the contract is not in my name and then add my number under which the phone belongs to. I was told I need to come into the branch AGAIN and fill in another form so they can do it again. they have inconvenienced me terribly because now I need to find a way to go back there start this whole process again and sit without a phone for another 3 weeks. I am disgusted by their service and their \don't care attitude"if I wasn't in a 2 year contract I would have taken my business elsewhere"""
