I just received my Vodafone bill and got a $202.69 add-on for 1,902,509 KB of national data on a Nokia 6760 on 15-Aug-11. However, the phone was used only for phone calls and e-mail so I am at a loss to figure out how one can amass that much use (the phone normally uses 8 KB to 215 KB). Called Vodafone customer service (India) and after 45 minutes had to talk to a supervisor (Kripa) as the original customer service agent would clearly not listen to my complaint. Received a call back from Kripa a few days later and stated that Vodafone investigate the charge and the data usage was from the phone and that I now had to pay the entire charge. I asked for the list of websites or other data sources where the usage was incurred from...she stated that that information is confidential and they do not keep track of that information. I know that all data backed up and monitored by government security agencies...so she was unwilling to provide me with any information on where the Nokia 6760 downloaded that much data. As they were unwilling to reduce or eliminate the charge which is a normal practice with US cellular carriers (including Vodafone's affiliate Verizon), I stated that I would pay the bill but complain profusely to others I come in contact with, as well as file a complaint with ACCC. I also switched out the SIM on the phone to a simple unlocked Alcatel voice/SMS-only phone as having a smartphone is a "ticking time-bomb" in American parlance to being assessed major league data charges regardless of whether one actually used the phone for Internet and e-mail or not!
