Samsung X820 — Bluetooth

I've bought the set Samsung X820 on December 2006.
1. The battery charger is not working anymore. I've complained about this on October 2007 to the authorised Samsung repairing centre in my city. Till date i have'nt received my battery charger, which has put me in a lot of difficulty.
2. It's been nearly a month my bluetooth stopped working. I was deprived o[censored]sing my bluetooth over the period of time. This, I had given a complain to the said authorised Samsung repairing centre, and i was told that a module of the bluetooth is not working. Then I told the engineer to replace it with a new one. But i was informed that it cannot be repaired as no spare parts are available in his centre.
I would like clarification and help on the matter.

Thanking You,
