Inconvenience of the highest degree

I bought my the phone at Totalsports in May 2018, and recently had i problem the phone doesn't charge i took it back to the store on 20/01/2019. I forgot to take my sim card out. it was sent for repairs after back and forth with Mobicel i was told that there is nothing wrong with the device, its my charge that has problem, Mobicel demanded i pay R170.00 for courier which i refused, finally Totalsport paid them . I received my phone on the 6th of Feb and sim card was not there. i bought a new charger phone still not charging
