Paddle.net review: ytd pro 2 yr subscription that I paid for

I brought on line from Paddle.net the
YTD PRO 2 year subscription with a card ending in 9546 on Nov. 20, 2021.
I paid $47.76 for it. I contacted Paddle and was sent to a different link to write a message. When I would put in my email address and then to do it on a second line it kept erroring me that bit was not the same. I did this over and over and I was not able to send the message. That I wanted a refund of the product. Then I saw that there is a great deal OF COMPLAINTS OF THIS Company.

Please try to help me.
