I fell for the trial scam and when I requested to cancel and get a refund, only the cancel happened. The support on the site was unresponsive until I posted in Trustpilot and appealed to PayPal. I was eratically replied to by Muscore support and asked to close my PayPal appeal to get a refund. Given that communication was weeks in between, I didn't trust Muscore. Eventually, PayPal closed the appeal and still no refund so I appealed again. Finally, I got the refund. This all took months. So, moral of the story is to hang in there until you get a refund. If you used a credit card, appeal the charge with them too.
