I have been usinh dna infotel from last 1 and half year.I have taken 6 monthly plan which costs me around 2500.
I have faced frequent disconnection problems many times.Once in every 3 months I face some issue.Apart from this speed is fine. Customer care service is little annoying.They need to improve customer service.
As its only well known internet service provider in this area they should focus on giving good service.
