Its a long story. Over a year ago I started of on 250 minutes and 500 texts for £30. I renewed my contracted and wanted an extra 25 minutes, for an extra £5. In the end, i was paying £35 for 275 minutes and 200 texts. I went onto the vodafone website and looked at other tariffs. I found one for 275 minutes and 500 texts for £35.
I sent Vodafone an email, stating that i was not happy. I had taken out two contracts, as my other half has got one as well. I threatned to cancel both contracts and go with anotehr company unless they changed it. I got a phone call the following day and he put me on that better tariff.
If i were you, go on the net and find a tariff. Phone them up and barter with them. Gurantee you'll get some knocked off or get some more minutes.
