Hi,I have BSNL broadband Home 500 plan.In August 2008 I got a BSNL broadband bill 26000/- rupees. I went to CRO and gave a complaint for the same and waited for the corrected bill. I got 30000/- rupees bill September. And went again to CRO, I got to know that they have converted my plan from Home 500 to Home 250. And charged for the night usage. They said they will correct the bill in October. but I got 6000+/- Rs. in October. I went again in December. They said they have not corrected the bill and correct the same in Dec. I got a Bill in December of Rupees 62000/- including all above bills. They sent me one more bill 60000/- and they claimed that this one is a corrected bill. I found there was a calculation problem and corrected bill came upto 55000/- rupees. I went again in Jan. They converted my plan and adjusted my bill to 31000/-. And they want me to pay it. I asked how could u change my plan and ask me to pay the bill. They say its their mistake but they have done the calculation on my usage and corrected the bill. I doubt on the calculation again. And they are not ready to show me the calculation. I don't know what to do and where to go. Please suggest
