You dont know how fraudulent are contractors in my place. Sometime when it comes to electricity repairs, they will replace your parts with something from them and at the end charge you expensively for it with out knowing that the parts they have put in is not new and already been used.
I agree on the above comment, here in my country they will replace things even it doesn't need. they will tell that it's broken but not. But project will fixed it because of the transparency of things.

Here in my work right now. One time we were out of the house for the whole day, when we came back home our main water pipe was gushing out with water. We wonder what had happened, it seemed that the pipe was deliberately cut. We found out that my employers former technician did it on purpose so he may be paid again for repairing it. Wise donkey

. It happened because they have a family technician for years and they trust him with out knowing he is frying him in his own oil.
