So far, I have never had a bad experience with them. I have been with HSC for just 9 months now, and they have always answered back with the right answers for my queries. 2 months back, my washing machine stopped draining water and it was not a pleasant experience. Within 2 days I had a huge pile of clothes that needed to be washed. I made a claim about it and they sent a service guy to check the problem and have it repaired.
They had to replace a part of the machine and everything was sorted thankfully in 4 days.
