Presumably the counter-signatory completed and signed section 10? From what I can see the copy of the counter-signatories passport does not need to be signed. So presumably they can simply email it to you and you can print it.
Although no direct experience with them, there are a number of services offering this. Here's one as an example;

VFS does not replace the need for a countersignature when it's actually required. They are mainly a mailbox. There is no actual requirement for you to meet them face to face.
The banks are matching your name and passport number against the mobile phone number you use. If they are the same no need to do anything. If not you need to update. My passport number was 1 digit incorrect, went into True and they corrected it.
