Hi thehed and welcome to the eForum
I'm sorry to hear that you are having problems with this. I can understand how frustrating this must be for you.
With the tests you have performed you have confirmed that this is a problem with the device itself. This will need to be sent away so that it can be repaired. All you need to do is take a look at our
Vodafone Repairs Thread for all of the information you'll need on how to get this fixed
Please let me know how you get on and if you have any more questions just give us a shout.
Thanks
Wayne
