Mousu.Art review for Discount Ninja Promo Engine

Customer service is slow and no solution is given still. I didn't need the Bronze Plan anymore so downgraded to Free plan so next month I won't be charged. I still had one whole month of the paid plan left but lost all the features. Support told me they don't have automatic downgrade like other subscription services had. I tried to go back to previous plan since I paid for a month the day before but it wanted to charge me again. I've contacted support for help and they said they'll contact the team and would get back to me with any update. It's been almost 3 weeks with no updates. I emailed multiple times throughout the weeks and got the same response.
