I see you've got a long thread about account issues here but if you want the best help from this community forum it's much better to start one single new thread explaining your issues. That gives other users (and staff) the best chance of being able to help.
I don't think you've mentioned about TV pixellation issues before, so I'll include my standard advice to anyone with these sorts of problems...
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 this will need VM to intervene. You're likely to need either an engineer visit or a replacement box, depending on what VM's remote diagnostics turn up.
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 ideally 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". Alternatively you can wait on here for staff to respond, which may take a day or so.
