bad customer service

I bought a 55" Samsung Curve TV last week and salesman who was assisting advised me that they don't have stock yet but the supplier promised to deliver on the next day, now its been 5 concequetive days I have not received my tv on Friday when I called the salesman said they still negotiating with Dion wired to give them the stock since they have but still I haven't received anything as yet. Today I attempted to call the head office in Durban I didn't receive any response instead I'm being transferred to the complaints department and they don't reply back I holded for 30 minutes.
