To get £50 off you need to refer a new customer though myself and I can process it for you
Are you acting in a personal capacity with this offer or an official capacity as an employee of VM as your forum login carries nothing to officially identify you as such as yet?
Without wishing to cast doubt on the claim in your signature of employment with VM, there have been a few cases in the past on here of people claiming to be VM employees, who were not, asking people to get in touch via private message to provide information.
Applying even the most basic online safety, exchanges of personal information via private message on the forum should only be done with VM forum team members who are clearly identified as such IMO.
Unfortunately, no one else on here will have any way of knowing or confirming this, other than taking you at your word, when you say you are.
If you are requesting forum users to contact you privately for the purposes of referral it leaves the door wide open for anyone, not employed by VM, to make an account (or accounts) on here and do the same thing. Those others may not have good intentions.
If you are collecting and processing customers', and possible future customers, personal information via a private user account and private messages on the community forum, then I'd politely suggest you are heading down a rather dark rabbit hole of possible data protection issues for yourself and for VM.
If you are a technician working from home and waiting to join the VM forum team on here, then you should wait until your official VM account is set up and you are identifiable by the VM logo and 'Forum Team' against your name before making such approaches.
