eph: Guys, the story continues - just received invoice from Vodafone for period 1/7 - 31/7. Why am I not surprised... Actually I remember the first invoice they've sent me was grossly overcharged as well it was over 300$ or something. Took me quite a bit of time to sort that out as well.
As per the terms and conditions up to 30 days notice is required to close an account,
What date did you request to close the account / change ISP?
