LG Electronics — washing machine repair has wrong receipt

Address:

560103

I got my washing machine repair done and paid service charge as rs 590 but received the e-receipt for rs 295. I called customer care to raise complain against the technician but to my surprise every time i call them they give a new number to contact and ask for correct bill. All my efforts are waste till now. They are a big cheater. Also customer care is pathetic and disgusting.
