Dell India — service quality

Address:

Thane, Maharashtra, 421305

I had issue with my dell laptop. I went to dell exclusive store at bhiwandi. I thought that it is a exclusive store as well as authorized service station. However, owner did not corrected me and proceeded with the servicing. I also found that they were also servicing lenovo laptop in the store. I am not aware that whether it is allowed to service laptops of other brands in the exclusive store. But i believe that this should not happen and if it is not allowed, please take corrective action. Also, after checking my laptop, they gave me estimated charges which was not acceptable by me. So, i asked to return my laptop as it is. However, they started asking diagnostic charges for checking the laptop. When i refused, they started behaving rudely and started arguing unnecessarily. So, i have 2 complaints
1. Servicing laptops of various brands in dell exclusive store
2. Inappropriate behaviour
