Adobe Stock account not cancelled and invoiced twice now

I have a Creative Cloud account with licences for Adobe Illustrator and InDesign. On 7 December 2018 I have purchased a licence for 10 Stock images for a specific project and R438.13 was deduced from my account on 9 December 2018. As have cancelled this subscription WITHIN ONE WEEK online via your cancellation system seeing that I do not need an annual subscription - the reason I also ticked on your system: the 10 images was just for a specific project.  As stated on your system, I am suppose to get fully refunded if I cancel within 14 days. I now received a notification from my bank today that another R441.78 was deducted from my account for my January 2019 subscription irrespective the fact that I have cancelled my subscription already in December last year.

I have AGAIN cancelled the subscription now on the system, seeing that I do not need the additional 10 Stock images and I also do not want to be liable for a cancellation fee, seeing that I have cancelled within two weeks since my subscription started. 

How can my refunds for the abovementioned amounts be activated seeing that there is no e-mail address available to contact with regards to this matter?  I will appreciate your urgent attention to this matter. Thanks in advance.
