Brought an umidigi x phone in december **** within * months it crashed so i did a factory reset and after it went dead buttons not responding. When plugged into mains the charging light is on but phone is still dead. The phone is in pristim condition no marks scratches and has never been dropped. *I emailed umidigi sent photos and video of phone as they requested but feels they are giving me the run around as its been over a month* *I loved the phone till it went wrong but lack of customer service and urgency to put matter right has put me off having a replacement. *I would like to send phone back and to have a full refund as im still without a phone nearly * months after this fault. Look forward to your speedy response to help me sort this matter and bring it to a conclusion. *Many thanks *Mr paul Moxham
