Had a similar terrible experience with crypto.com. After the MFA and stolen digital assets debacle earlier this year, decided to [hard/soft] delete my account with them. The company has a very complicated process for account deletions which involves having the account owner send a picture of themselves holding a sign. The picture must meet several criteria in order to be accepted.

The entire process took 45 days to resolve because their e-mail support is fucking terrible.
