Hi DrJazz,
You could try the text messaging service. Just send a text with a description of new remote 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 2 (TV Faults) but best to call at 8am to avoid call queues
For now you could try using the TV Control app until you receive a replacement remote
