We were recently charged an additional £200 pounds from vodafone for going overboard on the internet usage for 2 days. We pay £40 a months for 30gb internet but were charged £200 for 7gb extra usage. Yes, somewhere in the their 50 page T&C's this written in the small print but who reads those. We trust these large multinational corps not to use every excuse to screw their customers. If you try and speak to their customer service, they don't care.You'll be passed on from manager to manager without any assistance. If you sign up with vodafone, they will find some way to charge you a bomb. We have 3 family members paying almost £50/month. Some for the last 5 years. Over this tactic of robbing us £200 they will loose thousands of pounds of business from us. But they don't care, so best go with other providers.
