Contract from web order not honored

Another failed contract, I clicked to sign up on the 11 December, got all of the supporting documents, including contract terms and a start date and then was pushed onto an out of contract rate - no warning and no explanation.  When enquiring what happened and quoting the contract number I was told it "just didn't go through!!" and then I was forced to take a more expensive package with less services otherwise I would be paying 50% more until it was resolved.

Something very fishy is going on here, Virgin Media are breaking consumer and contract law and I believe this is all by design to extort more money out of customers.  It is not only unfair practice, but also illegal, you cannot just break a contract and say oh well that deal is gone now, have this new one which is less for more money!
