Hi,The MTNL guy came & installed triband connection on 21 Jan 06. Whereas when I called up 1504, they told me my a/c is being used from 14 Jan 06. Also I checked session history there was a use on 10 mb during the period 14 to 21 jan.I wud like to know was my triband used / misused by someone or MTNL guys. How was it possible cause the connection itself was given on 21st jan.How can I prevent this in future? I keep my router off when not in use.The website also does not show correct reading/usage. I should be getting 204 MB to use for 17 days (per day 12mb) But site shows total 400 Mb. Also 1504 helpline is useless. The too say u get 400mb.pls guide.
