I cannot becasue to access support you must be business admin and to login as business admin i need to receive a text message to the number i have not anymore.

It's a ckicken and egg, everything needs the message.

for me also delete everything is accepatble but still needs the text message

You don't need to login anywhere, there's a list of phone numbers you can call directly in the above document.
