Reliance Netconnect — Worst speed and getting disconnected frequently

I am using Reliance Net connect + data card. My number is [protected]. For the past 2 months I am experiencing the Worst Speed. It takes 10 minutes to load a page. I am recharging it with 800 ruppees monthly under free 5 GB plan. A minute after connecting, it stops either the there will be 0 speed or it will get disconnected. I am very much disappointed. I'd registered 2 to 3 times in the reliance cutomer care. But still no use.
