Thanks all it was just the fact that i was offered the upgrade without asking then i called up and posted here about being tied in and i was re-assured that i wasn't tied to a new contract (this was before i got the hub) and it was on my account .
Just should of not believed them (especially after reading posts about them).
Never got a letter to explain my new terms
It was just a heads up to warn anyone caught out.
Thanks
Robert
