What happens to my 120 credits after I cancel?

I've been paying for a 10 asset package (£23.99pm, I think) and I haven't been using the credits. I now have 120 credits but I clearly am not using this product so I want to cancel my subscription. I am not willing to loose the 120 assets that I have paid for. What happens when I cancel? Can I still access the 120 credits in my account?
