Phone sent in to repairs for the second time

In April I got a Samsung A5 on cellc contract. 25/05/2015 my phone was booked into repairs for a problem with the screen. ***<br> 04/06/2015 my phone was dispatched and the reason for the faulty screen was stated as a \faulty wiring connection". ***<br> 04/08/2015 my phone is booked in to repairs for the EXACT SAME REASON!!!!!! ***.<br> This is unacceptable to make me wait for my phone to be sent BACK to repairs department and not even offer me a replacement phone!!!!!!<br> This phone is not even 6 months old"
