I got along with Vodafone OK for nearly 10 years but every now and then I would notice their direct debit get bigger on my bank statement - they don't tell you when your contract expires and apply 'standard' (read rip-off) charges. Normally I would phone up and shout at them and things would go back to normal. Not this time. Several hours of being kept on hold and going around in circles with arrogant half-wits in Egyptian call centres was too much for me. I got a new, cheaper, contract with Tesco. Even then Vodafone made it very difficult for me to transport my number until I drove 10 miles to a shop. Absolutely shambolic organisation: I can't believe anyone is coordinating it.
