So I am under debt review my debt management team made an agreement with Finchoice the letter was sent and told not to debit my account . Yet two consecutive months they into my account and debited giving me some ******* turn around time that I should expect my money back after 21 days I refuse to wait that long after I was inconvenienced with my money . Finchoice I want my money back and don’t even think to debit my account ever again just do your job !!!!
