Address:

I have purchased a dell laptop model INS 5567 on[protected] from DELL exclusive store Sadashivanagar Bangalore560003. It is having OS windows 10. This laptop is very slow. On enquiry from the store, the guy said this model works very slow, they can't help. You can't imagine it is slower than the laptop which I purchased 12 years back. Kindly help me
