Cancellation

Hello,

I ve made a free test of signature which would spend for 7 days (start day 12 may 2022). At the same day, i realize that signature not make possible to do what i was intend to do, i cancelled it. But ive check my credit card account and i see that it is costing me the per month signature. Since i am in the 7 days free test, i would you like you refund me the cost it is taking. 
thank you very much
