Poor Customer Care and Service Delivery

My TV has been booked with Hisense from early December, following the updates they sent me indicating that the repair has been completed i’ve been try to call and make follow-up. The customer care is very poor, the consultants at the switch board are worse when is comes to client service. Its been 2 weeks now making follow-up and its either my calls are answered and i am put on hold till the call hang up (an average of not less than 30 minutes, today to be precise 38 minutes) or i am told that they will check the technician and revert to me which never happened. Worst service i have ever received in my life!
