Issue with Billing

I cancelled a subscription on the next day of a 7 day subscription and received a cancellation verification and have been billed at least a dozen times after receiving the in time cancelled email. My credit card company stated that Adobe has used at least 5 different Adobe names to force a payment to go through even though Adobe was blocked by them from trying to get a payment. I was forced to cancel my credit card in order to get the unauthorized payment attempts to stop and even after that I received an email from Adobe that I needed to update my payment method because their payment attempt was again declined. The attempts have been non-stop since the 21st of January and up to three times a day everyday. And has been impossible to notify Adobe to stop this practice as it seems they don't want to be reached directly and that this may be going on with numerous other subscribers thereby wrongfully taking payments from those who have canceled within the 7-day trial period and in my case it was less than one day after I signed up because the app did not work for me and I found another way to do what I needed to do. Adobe I'm sure is aware of this and I don't believe it's just an innocent bug I believe this may be intentional to pad their bank account.
