Dissapointing customer service

If homechoice customer service was as efficient as their sales department life would really be great. I called this morning to advise that the JVC TV I bought there is broken and I needed help or advice, I spoke to Unathi who put me on hold for a long time until my airtime got cut off and no decency to call me back, I send please call on the website, a lady called and promised a call back and it never happened. I called again spoke to a consultant and bagged her to call me back and she promised to do that and she never did. I send another please call at about 15:00 and nothing happened yet Homechoice will call you daily to advise about the sale but when you need them, they nowhere to be found.

I've been a good client for years and never had I missed any installment but this is the treatment I get?
