I would like to cancel the purchase I just made

As per an email I received for a 2-year CCleaner Professional bundle offer, I canceled my current subscription and purchased the offer. After the purchase, I realized the other products in the bundle are for PC, but I am on a Mac.

I would like to reverse that purchase and resume the previous subscription.

I just successfully deactivated the subscription through Cleverbridge. Now I need to see the charge reversed on the credit card.

You might have better luck by using the form here:

Hi @mshrabel,
Your recent CCleaner Premium purchase covers PC, Mac, and Android, so you can enter your new licence key into your CCleaner installation to activate your new licence.
