Yotpo: Loyalty Rewards Program

I have submitted 2 tickets and have waited over 5 days to hear back from you with no effort to assist me. I have been using the free version for over a year and while editing my settings I accidentally upgraded to the $29 paid version I noticed within the hour and downgraded back to the free version. However on my next shopify bill I noticed I was charged the $29 MONTHLY fee even though I was upgraded for less than an hour. I have asked multiple times to offer a refund and no one has gotten back to me. Pretty poor customer service.
