Hello,How safe is 1 GB limit for a month. How much bandwidth is consumed for a regular surf of say one hour. Also can anybody tell me the recent free call announcement by BSNL for august connection holds true.I just got the connection, I want to know what should I do and what not to safely lie within the upload/download limit. And more thing for wrong billing of broadband whom shall i contact. How they redress this issue?I also want to know if there is any error in connection or if any fault develops do their engineers visit the site to correct it like in telephone they do.Please Help.
