The problem is that to be able to temporarily use it so I could download my data and delete my account, Ill have to give them credit card details and pay them. Not doing so they would make sure to legally copy everything I have so even if delete the account later they would say, "you agreed to use jt for free amd we normally keep the data for x years after you leave".

you are already fully doxxed in the data anyway probably, if you have more than a few selfies. and plenty of text to fingerprint your vocabulary off. just pay their fee for one month, download the data, get it stored on something permanent (flash disk just for the job) and be done with it.
be happy that you still can do it. move on. these systems are enslavement grids.
