I'm afraid you need to bite the bullet. Grab a six pack and some nibbles and contact the regrades team if there are no options showing in your account. They have the systems to check what's available and then you can negotiate a new deal with them. You don't have to take TV and/or phone with the speed increase, however adding a phone often works out cheaper even if you don't use it.
You could try the text messaging service. Just send a text with a description of regrade to 07533 051809. Your message will go into a queue and a representative will respond to you as soon as possible. It may take a few days.
You can also call 150 from your Virgin landline, or 0345 454 1111, options 1,1 and 4 (Changes to your package) butbest to call at 8am to avoid call queues

Almost certainly not stuck with 200, but because of VM's wanton refusal to allow customers to manage their accounts online, you'll have to phone in. Since they're making it difficult, make the most of the time you'll have to invest and choose options for "about my account" and "thinking of cancelling", and tell the retentions agent that you're minded to take whatever the best BT offer is on Uswitch (look it up beforehand), because although you like the speeds of VM, you find that the speed/price balance is very poor. See what they say. They'll blather on about how they offer the best speeds, listen without engaging too much, if the first offer is only two or three quid a month off, ask 'em "surely you can do better than that?". You might get a discount offer, then say "that sounds a bit better, but still £000 more than BT over the next 18 months of the contract, if you can do that price on 500 Mbps then have we've got a deal?"
Keep it all polite and friendly, and don't accept an offer you don't like the sound of, nor any bundled content that you won't use - it just complicates things.
