Overcharged me for UK Data. When I queried the charges and asked for a statement that provided evidence for these charges they said they couldn't for security reasons. The customer service support guy's validity for the charges was a repeated statement that 'I'm sorry the charges are valid' - yes but where is the evidence... Not only this, when he read out the charges for my account, the numbers didn't even match the numbers I could see on their website. If that doesn't show they made them up then I don't know what does. Will be leaving the company as soon as possible and spreading the word that Vodafone exploits people's trust in the charging system and outright robs you with no supporting evidence to explains their actions.
