MTS Blaze
Mobile broadband price increment and poor service

I purchase MTS MBlaze prepaid dataCard in 1700 in november at that time it provides net in 499 3 gb. Next I recharged in 450 1.5 gb in 2 of december. Now in jan they increase thier price to 348 rs for only 512 mb.

So i want to ask from mts if their any rules and regulations or not price increment or they have any policy for their client to use thier poor service.
