To clarify, we would never charge you twice. If you think you have been charged twice, please do reach out so we can take a look and clarify this for you.
One thing you should know is that because you have two credit lines with us - a credit card, and a store card - this also means you have two repayments due every payment cycle.
Your credit card balance - if any - must be repaid weekly.
Your store card balance - if any - must be repaid monthly.
Details for what date each repayment is due are in the Bits app.
