Double charged - HELP!!

Hello dear community, 

I am using Adobe Premiere since a couple of months (28, 28 Euro monthly). And cancelled it in April. 

Now I detected that a similair amount (23,79 Euro monthly) was deducted from my credit card since last year November on top of the amount I paid for (mentioned above). Meaning my account was double charged (thats an additional 190,32 Euro = 213$), for a service I never used. 

Customer care (help), is telling me that my credit card was used for two adobe accounts. The one time I am aware of, and the other time, they are saying its with a similair Email address (just spelling of my first name is slightly different..the rest of the Email address is exactly the same - however, they wont tell me what Email address it is). The agent is telling me he can manually stop that my credit card is being charged but cannot confirm this transaction to my Email addreess, as he could only do that to this suspcious other Email adress.

1. OK - its hopefully being stopped now

2. But how do I get my money back?, this is a SCAM for me (I am 100% sure, I dont use any other Email adress with a similair first name, and also I did not use 2 Adobe accounts at the same time).

All very supiscious and I am seeking for any valuable advice. 

Thanks!
