It looks like your account was deactivated. You can try to contact the Care team and see if they'll appeal their decision, but that's ultimately why you're not able to withdraw.
Do not blame the site system for everything and try to find a catch. It would help if you kept a closer eye on your accounts on a site that can bring you income. But as far as I understand, this problem can be solved by contacting the ibotta support service. I admit that I've been in similar situations twice, but on other forums. Then, the only thing that helped me was the fake phone number. I didn't want to waste time on the proceedings and disabling the account, so I used this service. Perhaps it will also be a way out of the situation for many.
