I have had huge problems with Vodafone. I was unfortunately brought over from Dot Mobile when it went into administration. I'll cut a long story short- over about 3 months of dealings with them I found the only way to get anything done was to keep asking the customer service for their manager. Start out with the normal call centre employees if they cannot help you, ask for who controls their department, their building etc. If you keep persisting they have no choice but to put you through to someone who has some power. Unfortunately, the managers seem much more snappy and rude- really get on your nerves, but keep a level head and you can get somewhere. If you bring up the fact that you will be taking legal action as they have fraudulently entered you into a contract and charged you said fees, they will eventually put you through to a department that can help you. Once you get through to someone who has some power things get nice and easy, I even ended up getting compensation for my troubles.
