CBX Xtreme from Mallu Motors

I had bought CBX Xtreme from Mallu Motors (Kolkata, Park Street)
I have given my bike for first service in their own service station. My bike number is WB-07 Y3959. It’s been over 2 months and I still haven’t got my bike back. It’s been a very horrible experience as I keep calling them every week and they always tend to extend the time without taking any initiative. I have not bought my bike for the service station people to use it. I am a lawyer by profession and I going to file a case in the consumer forum to ask for compenstaion. I do hope for your early reply as I have’nt got any feedback from your side till now. Thanks
