Feeling like im ****med

I took the insurance over the Phone for my mom whom i bought a car for, all to find out she already took 1 as well, so i tried to contact them which i failed because you cant get their number anywhere, to tried and explain the the situation and cancel, and i did not even finish the application, because they required pictures of the car and video which i did not send since i was not interested anymore, but still they deducted the money month end, when i finally got a chance to speak to some1 on their app they told me they can’t reverse the money, because cancellation takes 30 days. I tried explaining that i did not finish the application process, meaning im not covered yet, but still the deducted the money, im really not happy
