Firstly the stock answer...
Pixellated pictures on live TV are often the sign of a signal fault. If you've rebooted your box once, then there's likely a fault somewhere, so call VM and report it. You're likely to need either an engineer visit or a replacement box, depending on what VM's remote diagnostics turn up. They can do these while you're on the phone to them.
First check the automated faults line for any existing issues in your area that could be the cause: 0800 5610061. If nothing's reported, assume VM don't know about your fault and you'll need to call them.
150 from a VM phone, 0345 4541111 from any other phone - choose the options for "I have a fault with my TV service"
Specifically in your case..

If there any network issues, they should be listed on the automated status line. 0800 5610061

Is there an email address where I can report this issue? Or I just have to cancel their service and move on to some other who can answer their customer's queries and fix issues?
VM have never had customer-facing email. Whether you call to report the service fault and let VM investigate it, or whether you're calling to cancel (assuming you're out of contract) you will need to call Virgin regardless.
The only exception is if you wanted to give your 30days cancellation notice by post.
