Is there a way you can remove your credit card from iTunes/apple

Did you check, if you can cancel the subscription or purchase, after identifying who is charging you?

If you see 'apple.com/bill' on your billing statement - Apple Support

If you want to cancel a subscription from Apple - Apple Support

In case you purchased directly from a company and not Apple, you will have to contact them about canceling.

I request and is not refunded.

Refunds are not guaranteed. For more information, see the Terms & Conditions.

If Apple has notified you that it is not eligible for refund, we can't help you, sorry, we are also users of Apple products & services like you. 

Some purchases are final.
