Renewed and did not need to do so

I followed an ad for 9 months of CCleaner Pro for $10. It was disturbing that I got an order confirmation saying that this product would cost $74.85!

When I followed the directions to register this new subscription, I discovered that I already had CCleaner Pro and it has 256 days remaining on the subscription. There is no obvious way to extend the subscription. Can I cancel the new order?

Since there is no topic into which this question fits, I selected SOFTWARE since it's software that I just needlessly bought.

Thanks for your help!

Please contact support at support@ccleaner.com they can help by either providing a refund or license extension (or other remediation that they come up with).

Where did you see this ad?

9 months is an odd number, standard CCleaner licences are for a year. (and $75 is too high).
