I strong requested them for a refund or a replacement? they wont share me the packing video, why? does the company has no basic integrity in selling., I went by the reviews and landed in this condition of turmoil where i cant use the laptop for my personal or business work. what can i do?

How many times do i keep following up with techyuga? are they playing the fool with me? If a customer is paying **k for a laptop why will the customer damage his own laptop, how will this solve his purpose? if extra care would have been taken, they could have couriered me my laptop and won a happy customer.
