I have taken hathway broadband connection on 9th of february 2016 .plan 650 which the company promised of 15mbps netspeed upto 75 GB and i almost made downloads of 12gb and okay if they calculated even for the browsing so lets consider it is like another 10gb but now my net speed is like 800kbps-960kbps and this is the worst service i had ever seen in hyderabad though i am using internet from past 8 years.For every 2-3 days my net keeps on disconnecting and i have to call customer care and they clear it by taking a whole day and the same is happening again and again
