My phone cannot male calls or receive them as my sim keeps disconnecting and saying nit registered on network !! I took it into currys who said its because my battery is o reheating but I had my phone inspected and fixed 8 months ago in currys due to a faulty handset when I signed up . I've argued that it still overheats but was fobbed off now it's out of warranty currys state its not co red fir repair but the battery and maim board do need replacing
I am still in contract for 2 months is there anything that can be done
