Hisense utterly poor service and Customer care

Absolute no customer care. SmartTV in for repairs on2 weeks ago. Received many e-mail and messages from their service providers (2 of them) in Centurion that it was a complete repair i.e. AEK domestic and TG VISION TECHNOLOGY SA (PTY) LTD. It is now the third time they try to repair it. The colour white and other reflections is reflected as green. Tried for three days now to contact the customer care line but no response. Send 3 e-mails on the matter and the only response is recognition of the e-mail. Once I get somebody to talk to on the customer care line. they just greet en then nothing. I hold the line for 5 minutes and hear the person breath but not talking. then the line drop. If I call now and press 1 for service, some music play and then the line drop
