Charged for CatLight but we don't use it anymore

Hi

Yesterday I received a receipt in my email for an automatic renewal of CatLight 5 Users (Annually) licence.

However, we haven't been using CatLight for quite some time now. 

1. Is there any way we can receive a refund for this last billing cycle.

2. I couldn't see any way on the website to cancel the subscription (although I have unchecked subscription renewal)

Ideally, we'd like to cancel our account completely so that we don't need to think about it anymore. The product is good but we just don't need it anymore.

Regards

Dylan
