Well done Nicola, but my real point wasn't about the upgrade; as I said, I was disappointed to be told 'yes', then later told 'no', but I'm a big boy and out of contract, so could go elsewhere if I wanted (but ironically I was actually trying to stay with them!).
My real gripe was what happened after that; a new customer could get a far better deal on a 12 month contract (€20 v €130) than I could as an existing one, and then to be told that if I left and came back later as a 'new' customer, to try and get the same terms, I would enjoy having a €400 security deposit slapped on my account!
I am amused too by how many negative experiences other former Vodafone customers seem to have had.
Very poor and short-sighted business tactics in my view!
