Ford India — Ford Aspire/ Pickup and acceleration issue

I have a ford aspire car run almost 48000km. Now, I am facing issue with pickup and it's acceleration. When I start and accelerate it fully but car runs at 10kmph and if I accrelerate it by pressing clutch, rpm doesn't increase. I complaint it so many time to adiv ford ghaziabad but no action have been taken by them. I started facing this problem when they repaired my car few months ago. My car mostly stays with them since then. I have spent so much my hard earned money on my car but they were unable to resolve it. Now it's ac is not working as it used to be. Once I was facing problem with my air duct, it was loose and causing some kind of sound, instead of changing it or place it correctly, they have rapperd it by some kind of foam and then applied some kind of glue on it. They return your car dirty and ask you to bring next time for cleaning. Always miss their deadline to return the car.
