Pathetic service and numerous lies on after sales support

Pathetic service. I called in on the 9th reporting a fault on my Hisense TV I purchased and was informed that it takes 3 - 5 days for a technician to come. I called on 13th to follow up and the story changed to that it takes 3-5 days for a technician to contact me. After numerous complaints Vusi called me to check it the technician contacted me and promised to call back as he had arranged with the technician to come on the 14th between 9 -12midday. ALL LIES LIES LIES. No technician contacted me and no one came. Pathetic customer service. Just want to return the device.
