As per the INKPAY Terms of Use:
Any refunds, credits or cancellations are subject to the refund policy of the tattoo studio. We accept no liability if the tattoo studio refuses to refund you all or part of the purchase price.
You can ask us to terminate your account or payment plan at any time. You remain liable to make your payments and pay the late payment fees(s) above in respect of any payment plan you have entered into. If you terminate a payment plan, the outstanding debt will be immediately due and payable.
If we do agree that your purchase is to be refunded or credited, you will not have to pay any further payments related to the payment plan, and we will refund each payment you have made under the payment plan including any late fees you have paid.
If we refuse to refund or credit your transaction despite you seeking a refund or credit, or disputing the purchase, you must pay all amounts due under this agreement without setting off the amount you believe we owe you and without counterclaiming from us, except to the extent that any right of set off you may have cannot be excluded under any law.
