Help! Credit karma just closed my account. They won't give me a reason other than the bank can do what they want. I just got my advance on 1/23/24. Used the card that day. Checked my app this morning, realized it was closed. Spent hours trying to figure this out and have come up with nothing. Can't get anyone with credit karma or IRS to talk to that know anything. What happens about the advance repayment with SBTG???? How long does the check take to come? They need SUED!!!!!!!
