I recently upgraded my phone and have had no end of problems. They sent the new SIM card and no phone and this took multiple calls to customer helpline to sort out of which of course I was charged for the calls even tho it was their mistake and they assured me they would wave the call charges. That is now sorted only now I discover they have had "problems with billing" and have added 2x 1 off charges to my phone that they shouldn't have totalling £65 however after 1.5 hours on the web chat they refunded me £30? What about the other £35?! I would definitely recommend staying well clear of Vodafone, they are shocking... Go with O2...
