HP India — HP spectre laptop service

I was referred to HP service centre Whitefield for getting the display of my HP spectre laptop fixed. The person who I handed over the Laptop was Charan whose phone number is the contact number for the service center. He took a few months to repair my display and finally when I got my laptop back the power adaptor was lost and he gave me a low quality adaptor. This is a very common happening in all HP service centers, they generally lose your adaptor and claim you have not given it. Later considering that the laptop is expensive I had to order for a new power adaptor as I was getting the message the power adaptor was not compatabile. Charan told me that he will help in mobilizing the battery and power adaptor. It has been 3 months now and he has not given the adaptor. The invoice he gave me was not with a HP address but someother address,

This person and the HP suppport service center processes need to be fixed
