Unable to Access New PayPal Account Due to Deactivated Phone Number

Hi, I just opened my PayPal account, but unfortunately, my mobile phone number got disconnected a few days ago. Currently, in order to access my PayPal account, I am prompted to send a message to my previous phone number, which is no longer in use, to finalize the login procedure. Unfortunately, as my number is no longer active, I am unable to proceed. Could you please help me with removing my outdated phone number from my PayPal account? Regrettably, I have been unsuccessful in my attempts to contact customer service through any means. Could you kindly assist me in updating my phone number and accessing my account?
