Reliance Broadband+ — i'm not getting speed what they are showing in their advertisements

Address:

Pune, Maharashtra

sir/ madam,
I bought reliance broadband+ in the month of december-2009. As they are showing in advertisement that they provide a speed o[censored]pto 3.1Mbps, but i always surf at a rate of maximum 10 to 20 Kbps. I registered complaint several times but they told me the basics that is, to clear browsing history or uninstall the software and then reinstall it after restart of laptop.
I'm facing the same problem and they are just so casual, besides I'm paying large amount in billing.
kindly help me out.
