Worst Service

I took my phone in for repairs in April 2015 as well as put in a claim with the insurance immediately, i was then contacted to and told to pay the access which i did, sent the proof of payment through to the insurance and i am shocked to find out on my follow up the claim status in pending excess amount outsanding. This means no one recieved my proof of payment over a month that i had sent it and meantime the Repair Centre claims that the phone is repaired and they cannot dipatch the headset until it has been paid for. i want to cancel my contract because i am currently paying with no benefit. There no communication from them at all about this till June 2015.
