Panasonic — services not good enough

We had purchased a washing machine. The machine had some problems. We called the people from panasonic. They came a tried to fix the machine problem. They told that only a small problem is there and will be able to fix it. Now they tells that the machine has a lot of problems and asked us to pay a lot of money.
This is our complain. That the service provided is not good so please take the initiative to provide a better service.
