Consumer Redressal

I have a BSNL Broadband at my address. The connection is not working for a long period of time. I am not able to use the landline for twenty days in a month but i am charged for the entire month. Some equipment installed at my address is not working properly. I asked the concerned people to change the equipment but they are not willing to do so. I beg you to kindly look into the matter and ask BSNL to not to charge me for the days i am not able to use internet and take neccessary steps to resolve the issue as well.
