Worst customer service ever

Bunch of useless people that are working at Hisense. the first ticket was logged via fnb as I bought the tv through them, a few days later someone from the Polokwane branch phoned, I'm residing in Pretoria and this was stated clearly. a few days later I called again as no one phoned me again since the first call. I then changed my number with the service agent at Hisense. then a few days later again someone from the Johannesburg branch phones me, again promising someone from Pretoria will call back. Once again I had to call in asking again for someone to call me back. guess what I'm still waiting for the first call from a tech in PTA, it's been almost 3 weeks later. I have spent more than 30min on the phone already. Please can someone in management please call me. reference numbers: *********

As im writing this its been more than 24hours since i was promised my first call from a manager, almost 3 hours since one of their representatives promised someone will attent.
