Hisense, Useless, pathetic service!!!

Useless!!! Fault reported around April, still not resolved. -Minimal to No feedback from service centre and Management (Renata, Santie). If the client does not ask for feedback, no feedback. -Technician(David) lie about the status and arrival times. Will schedule appointments only to never arrive. -Cannot repair a basic fault(button not working), expect me to pay in to get a replacement after they awarded a credit. -By far the worse service ever experienced!!!
