Muscore Auto Renew Pro but not wanted.

A month ago I tried this service on the trail period and about a week after I figured It wasn't for me and haven't seen or used it since. A few days ago It auto renewed and charged me a years worth of pro subscription. Is there anyway I can get it to refund or change to the monthly plan instead so I can just pay for this month and cancel cause I can assure you I haven't been and I'm not going to be using this website at all.
