LG Electronics — Microwave in service centre from 2 months

We have given lg microwave to service centre in month of march and still we have not Received oven back. Always they are giving reason for receiving damaged spare parts and rudely speaking. When we gave for repair next day they called and asked it will be charged 2000/- for spare part to be changed and we confirmed. Every 3 days we call and ask for status and we get in return will call u in 5 minutes. We are facing this mental harassment as we have to go to service every 2 days centre which is 20 kms from my place. We are always being said spare parts are received damaged and its already 2 months. Neither company toll free number works neither service centre owner gives higher authority number’s to speak with. Ladies staff are always rude and cut the call asking to keep call on hold. We feel we are being cheated and something fishy as no reputed company service centre takes so much time for service or give such worst services. I hope my problem will be solved.
