Synergy Systems has poor customer service. One of my very good frnds had to yell at them for abt 15 days continuously to make them start working on her complaint. These guys don't stick onto deadlines and I personally don't have a good opinion abt them.

Thanks..sreejas..

You can try Synergy Systems @ Valluvar Kottam high road, near the Independence Day Park. Our company purchases laptops from this place, their service is good and you will be able to get the stuff at a price little lower than the website price.. Contact Person and Ph: Anitha, 9841934193

Ritchie street? I think you get good stuff also if you are willing to pay more. Not very sure.
