Two things get my goat. Being ripped off and being ripped off.
I have two telly boxes from Virgin Media. I get the first one, a V+ box (PVR, HD etc.), for free as part of the XL deal and am being charged £15 a month for the other non-V+ one. Only when I checked their web site it turns out I'm being overcharged for that 2nd box. Grrr!
My solution? I've got them to upgrade my 2nd box to be a V+ box too. So I'll have two. The total rental cost will only be just £5 a month. Saving me £10 a month (for much better kit)! Ha!
