Refund from Just Answer connected by Apple

I bought a new Magic Mouse yesterday at Apple Store. Being told to connect it to back of Mac using the cable came with mouse, I did so for several hours but got the message USA Accessaries Disabled. I got a chat with Apple support, but she could not help and sent me to the Link to Just Answer, saying it will be $1 and fully refunded. They charged me $45 instead and was not helpful at all. (1st agent said she has to ask that question to her supervisor, and a few hours later I got new text message saying connect the mouse with another device. I however already did that by myself before I got the answer. The mouse still did not work ,and I read the instruction through the Apple Support to turn on and off the mouse, and it is finally working)

I want a refund of $45 from Just Answer, for it was useless, and why the charge is $45 though Apple Support said only $1 and refundable???
