Bilt Rewards won't delete my account

Here is a true story.

I was told I have to pay my rent using Bilt Rewards moving forward. I signed up for Bilt Rewards. I provided only phone number for verification, and after verifying i was taken to a page that had all my credit cards. Like, all of them. It asked me which ones I would like to associate with rent payments.

I never used Plaid on the Bilt site.

I went to the payment page and added a checking account and tried to make a payment. Bilt said I didn't have enough money in my checking account to make the payment. (I was going to transfer money into the account afterward.) I never authorized Bilt to monitor my bank account information.

So I tried to have my account deleted. After following a few different steps involving customer service, they said they would close my account. I said this was not good enough, I need my account deleted. My fear is that they will continue to monitor my accounts and my credit cards even though I never authorized them to, and they will continue selling this information to others.

I've gone back and forth three times asking them to delete my information off their servers. They have now closed my account, but they still haven't deleted it. If i try to log in to my account, it just says my account is "locked." So I'm probably in a worse position than I was before. My account still exists and is likely being monetized, but I can't even see what information they have on me.
