Query: Faulty Piece

I am not sure if somebody else faced the same experience. When I bought this phone, I was successful in registering the cordless with the base. The phone worked fine for first 2-3 days.Later, I started getting the 'System busy' message. When I tried to re-register it used to give me Error!I had no choice but to return the product.
