Bigrock as the name suggest is like a rock. Whatever you do to get service out of them you will not receive anything. All tickets/escalations will be responded with "We do understand your concern." and "your patience is highly appreciated." even if they take weeks to solve your issue.
It felt like a grave mistake we made buying the space with them when our customers were yelling on us for the issue and all we could get was this in response from there tech support team, they still have not solved the issue. I doubt on how they claim to be the number one hosting company in India. Did a big mistake going on the brand on Direct and landing on Bigrock.
