On 7 December 2016 I purchased an Adobe Stock subscription for 10 images per month for a year (order number #ADD000320780AU). I wanted to try out the free trial and see if it was for me. On 12 Dec I was charged $31.89 AUD by "Adobe systems software 044-207-3650, 1211". I do not know why this is. Was I charged for Adobe Stock? I thought the first month was meant to be free. I have cancelled my Adobe Stock subscription on 13 Dec. Can I get this charge refunded? Thanks.
