hi, I think still lot of people use voltage stabilizers, although the other products that we buy (TV, fridge etc) come with internal stabilizers. We also have, and after a really long time, one of them stopped working. After making a couple of calls, I finally located the service center. This one is a small place in Jayanagar East (near Pump house bus stop). I could see that there were a few people working there, and the front desk man was very polite. He had been attending my calls, telling me how to reach the place, without getting frustrated. When I went there also, they were very polite and professional. The attitude towards their work was very laudable. They took my stabilizer, gave the standard slip and asked me to call the next day. And next day, it was ready for pick up! I was very happy with the service mentality of a service center - finally !!
