Terrible customer service

My TV was collected for repairs in August and Hisense is as quite as a mouse. I made several calls to check status and have been sent from pillar to post ever since. The "manager"responsible, Mr Morne Rusty, is very rusty to say the least. He completely ignored my emails, SMS's and WhatsApp messages after he committed via WhatsApp that the TV will be delivered. Keyde Mohlala from the "Hisense Service Team" has also learnt to ignore messages, probably learnt from Morne, who promised but failed to fulfill, not even a courtesy call to apologize or at least explain the delay. Good luck to Hisense's new customers!
