Refund Please

I have an indoor camera. I signed up for the FREE trial to see if this is something I’d like to subscribe too. . Upon putting my card information on the account it charged me $5.99 two times 10 minutes apart. How do I get a refund? I have emailed and was told I’d get a response in 24/48hours. It’s been well over 72 hours now. It’s been about 4 days. I would like a refund. Please and thank you!
