I really need help getting my account back

So I no longer have access to the mobile number associated with my PayPal account, I can’t seem to find anyway to contact anyone without logging in first (which I can’t do without that phone number) then I find out that I can call them as a guest, but before the bot will put me on with a real person I have to input the phone number associated with my account, which again I don’t have.

Any suggestions on what I should do next would be very welcome
