I have a big issue with our ADSL bill . We have a 3 MBPS ADSL line and our limit is 40 GB. In the year 2008 we have not crossed the limit except May . Only in the month of may we received a bill from Etisalat showing an extra data transfer of 224 GB (Dhs 22,000). We have a sonicfirewall in place and the reason what etisalat is saying is someone must have used our password. I have attached the bill received from ISP . Please explain me the possibility to get this reversed and to show our ISP this is wrong from their side.
