Hi Friends, I have this BSNL 500 Home plan....and it happened that, i downloaded files around 600MB, between 2:15 am and 7:45 am on Mar 9, and unfortunately it has been counted in the usage ... Although it shows as 0 in the last column (Traffic(KB)(excluding night unlimited[For HOME 500/1000/1800/3300 plan only])) It has been added in the total usage which shows at the top...Total Send Volume(GB) Total Receive Volume(GB) Total Volume(GB) Total Duration(hour) 0.305 1.203 1.508 148.26 I called up the help line number 16004241600 in bangalore and those guys told me that, if i download a file it will be charged...but, if browse any website, it wont be charged!!! I CANT BELIEVE THIS !!. I dont think the bsnl is so intellingent to prevent files from downloading and just give the access to browse websites .....In that case, what does "UNLIMITED DOWNLOAD" mean?I did try to search some of the postings in this forum, which are related to the same kind of issue...but i am not able to clearly understand....as some say, even though it is added, it wont come in the bill.Some say, they have been charged thousands of rupees...Please advice me!!Thanks in advance for your help- rajita.
