Login issue due to two-step authentication (urgent please)?

[Karat2]

I changed my phone number and the old one is no longer registered so I can't get a message. However, I still have an inactive prepaid number that I can use to prove my identity. I tried to call Customer Support at: 38680083096 but the number is not correct. At least that's what the answering machine tells me. I am asking for your help as soon as possible because I have detected illegal activities on my paypal account. That's what I was told in the email. Thanks in advance for your help.
