Personally, I'm fuming.
I phoned Virgin up a couple of days ago and told them that I had been sold an unlimited, unmetered package, that was no longer unlimited or unmetered, and whether they considered that changing the contract's terms.
The lady on the other end said "It was always going to change", which was never stated to me.
I'm not making a fuss yet, as we need the connection for a couple of months whilst the exams are running but I may well be busting a gut to get the contract terminated in June. The new limits make the service worthless
imo.
