Hi K2, I had the same. My mobile was included in my OOMPH package. All the contacts from Virgin said we would be moved over to O2 and everything would be the same - same package with no price increase.
This morning I get a bill from O2 for £24.98! I like you was not happy about it. I called Virgin she didn't help but put me through to 02. All O2 said was that I need to ring Virgin to find out how much I was paying them! Which was zero unless I went over my limit, which only ever amounted to £1 - 2 a month if that. So I called Virgin again... the female checked but could not get me on a package for less than I was already paying. Eventually I got transferred to accounts management (?) dept. He did go through what they could do for me and came up with a package that was everything I already have plus higher BB speed (1G) oh except a sports channel (TNT?) which I never use anyway all for £40 less than I am currently paying so basically covers the £25 O2 and still about £13 pm less.
So I have agreed to stay, but I was totally prepared to leave Virgin (and O2) completely.
So my advice is to get on to Virgin and ask them to lower your charges. First CS may not be able to, but they should pass you to someone else that can fix it.
Oh btw *faints* I have phoned Virgin a few times this morning to get this sorted but *faints* got through almost immediately, lol.
