Total nightmare trying to close a joint account - BEWARE if you have both joint and personal with SoFi!

I reached out to SoFi to close a joint account held with my ex. The balances on the joint savings and checking were zero. The transcript is below. TL;DR they closed my personal account with all my $$ in it in addition to the joint account, despite me telling them repeatedly that I only wanted the joint account closed. I immediately called as well, and they were unable to do anything about all the accounts being closed.

Chat transcript:

SoFi: Thank you for choosing SoFi! While I pull up your account, is there anything else you'd like to share?

Me: Hello. I just want to close my joint accounts (co-owned with my ex-partner) and do not want to close my personal accounts.

SoFi: Thank you for reaching out to us today in regard to closing your SoFi accounts. We hate to see you go and we thank you for giving us the opportunity to be a part of your financial journey. If you are interested in reapplying, we would be happy to have you back in the SoFi community! Please contact us with any and all questions going forward.

Allow me a moment to process the cancelation please

Me: Not the personal accounts, please make sure you are not cancelling everything. This is just for the joint accounts. I am not leaving SoFi. Please confirm as your message indicates all accounts closing

SoFi: Okay! I am processing the cancelation of the joint account, allow me a moment and I will be right back due to the system sometimes does not allow to cancel only one. I will be right back! Where should we send the account balance of $XXX?

Me: no no no those are from my personal account. I do not want my personal accounts closed. Joint checking XXXX has a zero balance, joint savings XXXX has a zero balance
DO NOT close my personal checking or savings. This is my primary bank

SoFi: Oh okay, the system it not allowing me to complete the closure for one account only. Allow me 3 minutes more please

Me: How does SoFi normally process the closure of a joint account when a member also has a personal account

SoFi: Where should we send the account balance of $0.01? I have fixed this matter immediate. The balance is actual 1 cent.

Me: ok, can you just transfer it to my personal account at SoFi?

SoFi: In our system, remaining balances can only be transferred to external banks. Would you like me to send the 1 cent to either of the linked accounts?

Me: [external account info]

Me: You are certain that my personal accounts are not being closed? This is my primary bank from which I pay all of my bills?

Me: My bank accounts are not showing any more

SoFi: Thank you for holding, Leslie! We have processed the cancellation of the joint account. However, because it was a joint account, the system proceeded to cancel both associated accounts. We completely understand that this was not the expected outcome of your request, and we have already escalated this system issue to the appropriate team to review these cancellations. Please note that deposits typically take 2 business days to appear, so your balance should be available to use in less than 2 days. We truly appreciate your understanding regarding this matter, and we will keep you updated on the progress of this report!

Me: Everything is connected to SoFi - all of my bill payments are running through my personal SoFi account. How are you going to fix this? I repeatedly said I do not want my personal accounts closed.

SoFi: We completely understand your concern regarding this unexpected closure. Because our system links both accounts under your name, the cancellation of one automatically caused the unexpected closure of the other. As mentioned, your remaining balance will be transferred to your linked [bank account info]. It will be available for you to use with no issues in less than 2 business days.
