LG Electronics — Complaint against after sales service

Address:	Kamrup Metropolitan, Assam, 781003
Website:	LG electronics

We have front loader lg washing machine, model no. Being f1480tdp25. Alspeil. Recently it stopped working so we raised a complain with lg company and accordingly service engineer came to visit n checked the machine. He than specifically told us that two parts are not working and as such, it has to be changed. He also told us that if we can produce the invoice of purchase, one parts will be free n the other parts will cost near about 3000inr. So we sent the machine to service centre for repair. First of all they took a lot of time to repair and we have to call frequently to ask about the washing mahine. Than one day they called us n said that machine has been repaired and we have to pay more than 10000 inr. When we told him dat the service engineer said it would cost only 3000inr.. How come its so high. He than said that they hv changed some other parts so its 10000/-
My complain is when the service charge is too high, how come the service people change the parts without informing me. Instead of paying more tham 10000/-i would rather prefer to buy a new washing machine.
After that, the service people didnt gv us any feedback about the machine and doesnot respond properly when we cal them. Its still lying in the service centre. Please kindly solve my problem or else i will be bound to escalate with your higer bosses.
