Electrolux India — Washing machine service fraud

Called Electrolux washing machine service center for repair of washing machine. The technician visited and took my machine saying it can be repaired at the service center only. After 4 days he brought the machine back and left it and charged me 10000 for the service. He said he will send the bill but nothing is sent to me till date. I am trying to call the company but they are not sending anyone to do the repair. My machine still has the same problem. Now they are not even answering my calls I am calling them on the numbers mentioned on their warrenty card.
