Cancel Subscription Of DreameShort

I had a 39.99 subscription with DreameShort and I wanted to cancel it, but I could not find any way to cancel the subscription. I no longer even have the application on my device, yet the 39.99 fee was still taken from me today. I do not know how to reach DreameShort customer service and I have not been able to contact anyone about this situation. I want my subscription to be cancelled immediately and I also request a refund of today’s 39.99 charge and any other payments that may have been taken without my clear consent.
