Me and my friend were staying in a room for 2 years at the time of college.
we cant afford an AC, that time, so we went for an Air cooler, which will fit to our budget.
after a seven or nine months usage I could found a leakage on the cooler and I informed the service center.
no one came,
I contacted again and again.
no response received .
its been 3 years now. and its in my garage.
not a good service folks .really
