Verification of my phone number impossible

Hello, since yesterday I haven’t been able to log into my account.

It asks me to verify my number, but when I enter it, I get a message saying that the same number can only be used once, even though I don’t have another account.

Everything was working fine until last night.

It’s impossible to contact Vinted; they always send me the same automatic message, telling me to click on my account icon, but I can’t access it.

Thank you for your help.
