My phone has been with MTN since 06 May 2015

I took my phone to MTN on the 6th of May 2015 for repair.The damage was a tip of an aux cable which had broken and got stuck inside.When i took my phone to the MTN store at Fox street they told me to come check after a week, i returned a week later and the phone was still at the store and hadn't been taken to repairs yet.I returned after a week and it was at repairs and i was told to return after a week again, i did so after a week and they told me MTN is on strike, which went on for about two months or so.MTN never contacted me even once to give me feedback on the matter.Its very frustrating and i don't know what to do anymore.Am paying for it each and every month but am getting nothing.my barcode number is ***, the phone's number is ***6,my email address is [Email Removed] contact number is ***.
