Phone in for repairs 3 times in 3 weeks

My phone switched off on 25 May 2016 and would not come back on. The Phone was booked in at Cellc Shallcross ref No. ***. The phone came back from repairs on 29 May 2015 only to find it had no audio. The phone was booked in again on 03 June 2016 ( ref ***) and returned to the store on today (15/ June 2015). <br> On testing the phone in the store it was found to still have no audio. The phone was booked in again. <br> On calling the customer care line i was told that they cannot help me as the contract was taken out at a store and not cellc direct. The store says that the phone will continue to go in for repairs irrespective of how many times.<br> In one way or another i am paying for a phone that is more in the repair shop shop than with me. I believe Cellc should replace the handset with anew one. All cellc management staff not available to speak to me at the call centre or cellc repairs, HOW PATHETIC.
