Repair not done after 6 weeks!!!

My SAMSUNG A5 was purchased 17/04/2015, the morning of the 1st December 2015 my phone did not want to switch on, later that afternoon I took my phone to a SAMSUNG Agents / Repair Centres in Three Rivers. I was told it is a software problem and they need to install new software on my phone. A few days later I was told that the Main board of the phone need to be replaced. The phone is still under warranty and will be replaced at no cost on me. <br> <br> Today, 6 weeks later my phone is still not repaired. I am without a mobile phone for the last 6 weeks! I am really disappointed and frustrated with this situation. <br> <br> And I am strongly considering it not to take a Samsung mobile phone with my next upgrade if this is the service that we get.<br> <br> I believe that this is a common problem, as a lady at my work is also battling with the same problem with her phone.<br> <br> I am insisting on a NEW Samsung mobile phone, as the A5 I only had for 7 months before the problem started.<br> <br> I would appreciate it if this matter can be resolved ASAP.<br> <br> <br>
