Godrej Appliances — Payment scam

I want to file a complaint regarding that my fridge had a problem and then I called in the toll free number of Godrej Appliances and they assigned someone from their authorised service center( A One Service Center)
. So the person came and resolved the matter but the thing didn't work out and the problem was there. He even gave his personal number to contact for further assistance . But when we called him he started to delay the thing
saying that he will come today, tomorrow but he didn't come . So i called the toll free number again and they said to contact the respective service center. The Service Center turned out to be false because when I called them on their number they said to send me the bill and i did it and they said that they will contact me but they didn't so i called them back but the number was switched off so i called on the alternative number and then the same thing he told me but he didn't as well so again i called them back but the number was not reachable. The part that the guy changed costed me Rs2800(shown in the invoice below). The service center as well as the deivery boy both are false. Please look in the matter ASAP
