BlaBlaCar Won't Verify Phone Number Tied to Another Account

While signing up for the BlaBlaCar app, I can't seem to verify my phone number. The system keeps showing a "This number is already registered to another account" warning, and I can't complete the verification process. Despite trying around 10 times today, the result hasn't changed, and I can't actively use my account. I'm requesting that BlaBlaCar remove my phone number from whatever incorrect or old account it's currently tied to, assign it to my own account, and make the necessary correction so I can use my account without any issues.
