I have a Vodafone contract which is ending next month. I called yesterday to give cancellation notice. They insist me to write a letter.
I know it's their policy but I had a few contract with T-mobile and O2. They are a bit relax on this issue and all these times I canceled them over the phone.
I am not moaning but it's their wish to tie you a few more days

After receiving my cancellation letter they started to calling me. They offered me a deal 500min xnet minutes + 250 txt + new mobile + 12 months contract for £17.50 a month. I haven't accepted it yet may be I'll ask for a good phone.
What do you think?

That's not a bad offer I think. Yeh, ask for a good phone and try to lower the line rental to £15

Ok, just upgraded.

500 min + 250 txt + Nokia 6300 = £10 a month

I am happy with it. What do you think?

Not bad, not bad, but i cant stand companies that insist that you have to send a letter to cancel. Feels like im being taken for a ride when I hear this.

not bad atall.
