At first the speed ,
You can get speed as your subscription
I have a subscription of 710 INR per month and it gives 2-3 mbps of average downloading speed . Sometimes the speed reaches 10-15 mbps , but that's for only a few seconds . There are higher packs available .
Now the service ,
You can trust the service provided by them . There won't be any problem . The internet connection stays good almost all the time . If there's any problem all you have to do is just call the toll free number of their customer service and they will tell you step by step how to solve those issues .
Overall a nice internet service in very reasonable price .
