I Was Charged by Cerebrum IQ Despite Free Trial Period

I tried two or three times to cancel my Cerebrum IQ Subscribtion, as I was under the impression that there was a free trial period. I kindly ask you to confirm the cancellation and issue a refund for the month of July to my credit card. Thank you in advance.
