What Our Customers Say
Real feedback from homes and businesses we support across Kolkata
A
Arjun Mehta
Small Business Owner, Salt Lake
My office laptop crashed a day before an audit. Sethy Tech recovered every file and had the machine running the same evening. Genuinely lifesaving service and very fair pricing.
P
Priya Chatterjee
Homeowner, Behala
They installed four CCTV cameras at our home and patiently explained the mobile app setup to my parents. Clean wiring, no mess left behind, and follow-up support whenever we call.
R
Rahul Banerjee
Café Owner, Park Street
Our billing systems kept dropping off the network during rush hours. They redid the networking properly and it has been rock solid since. Response time is always quick.
S
Sneha Iyer
Architect, New Town
Got a custom workstation built for heavy rendering work. Excellent component advice within my budget and the build quality is superb. It handles everything I throw at it.
V
Vikram Singh
Operations Head, Howrah
We moved our AMC to Sethy Tech last year and downtime has dropped dramatically. Their team handles our servers and printers proactively instead of waiting for things to break.
A
Ananya Das
Freelance Designer, Garia
Thought my hard drive was gone for good along with two years of client work. They recovered almost all of it and kept me updated at every step. Highly recommended.
