Incomplete name in P60

I have just found out that my name on my P60 is incomplete however on my payslip I have my complete name. Does anybody know how to update the name in the P60?

Hi Mhaey Calucag,
Please discuss this error with your employer to show the correct details. 
Thank you. 

I have ask them but this was the reply “ I can’t update the P60 it is created from within the payroll system at the end of the tax year. It uses the same name information that the payslip uses” i i tried reiterating that the names on the P60 is incomplete compared to my pays lip which has my complete name.

Hi Mhaey Calucag,
The P60 is provided by your employer so you would need to contact them if the details are incorrect.
If they are unable to provide a P60 they could give you a statement of earnings. 
Thank you.
