Zero problems while Marcus card was Capital One card. Marcus app and site refuse to let me link my bank account. Called in, had customer service link account, submit payment, and enable auto pay. Payment was reversed, bank account removed, auto pay disabled, no notification of this, only caught it because I track finances. Called in again, they don't know why payment was reversed or auto pay disabled. They re-setup everything, submit payment. Checked again today, payment is reversed, auto pay disabled, and bank account removed. Now I have a late payment and been on hold for 30 minutes. This app and card are garbage. Once I can get this stupid payment to go through I will never use the card again.
