Acer India — service request closed without service, by tampering carbon copy of the service report.

Service request closed without service, by tampering carbon copy of the service report. I have original!

I have reported the problem with my acer laptop repeatedly to various levels despite the fact that acer executive identified the problem. However, acer executives denied service repeatedly stating warranty was over. How can it be a reason when the service request was raised during warranty? In fact they agreed their fault each time during call but no action later.

Finally by tampering carbon copy of the service report they denied service. But i have unaltered original copy of service report
