I started to fill my application in November and on the end I had shortlist of what paperwork is required from me. Slowly I took the test life in UK, got all the p60, payslips, found referees, etc.
Now... I opened back my application few day ago and my checklist has changed ...
Required documents to prove my presence are:
Letter from employer, educational establishments or other government departments.
Nothing about p60 or payslip....
I checked the guide and it still says p60, wageslip allowed.
So I rang helpline and I have been told than I cannot provide p60, wageslip only what is shortlisted. When I mentioned guide lady told me in quite rude manner that paper application is different to online application and I should not use this guide as it is only for paper applications. When I said it is linked to this guide on my shortlist she repeated now very annoyed that only documents listed are allowed.
So I don't understand how paper application have different requirements to online applications?
I rang 3 other times to check whether she was just uninformed and all people told me the same that I cannot use p60 or payslip. Only letter from employer that states start and end day of employment...
Has anyone came across this nonsense? What is the right answer?

Ps. I'm eea citizen
