Some help with HMRC

Good morning folks so after 8 long months of waiting my wife got her visa refused beacuse the home office beleive I forged my pay slips my work contract and also bank statements the reason being is that there is no récord of me currently working but I have been empolyed at the same job for over 1 year every week I pay tax I pay national insurance and also a work pensión but for some reason the HMRC dont have me down as empolyed so once I fix this issue and reapeal our case I know that they will overrule the decsion and Grant my wife her visa so my question is what do I need to do as anyone walked this road before?
