[Resolved]  LG Electronics — Dishwasher repair service

I had registered for my LG dishwasher repair service online from my registered mobile. Service engineer B.Satyanaraana called on my reg number and came for service.He said motherboard needs to be changed for which we paid Rs 5925 as we were not having AMC. After installing new motherboard we were still have problem. We were asked to take AMC for which we paid Rs 6280 for which he gave a signed receipt on LG company sheet. Now when we want to avail service the said engineer has disappeared.Head office has said AMC has not been registered. No response from hyderabad service centre.
Even after repeated requests for service thereis no response. We lost money and time.How can LG company send such irresponsible people for service ? LG company must take note and refund our money back.How can they allow this to happen to customers ? ?? How can we trust this company? WE NEED JUSTICE
