Haier Refrigerator 275l — UnAuthorized Charge Made by Company Mechanic

Sir,
I am Pradeep Ranjan Behera from Mumbai. I purchased a Haier 275L refrigerator from Croma with having one year of warranty. But after 13 months it stop cooling and became an oven. I log a complain through company's toll free No and they send machanic. Every thing is normal till now.

Here I want to compalin about your service provider for making unauthorized charge he made me. He charge me 1400 Rupees for his Service and change the Timer of the refrigerator. As we don't know the price list so we have to pay for that.

Please take some action on such type of service monopoly.
