Temu - NOT trustworthy. BEWARE, they took money without authorization.

I have ordered some goods on TEMU, I did not finalize my order as I wanted to maybe add more items. I closed my computer and low and behold got a message on my phone that my order was ready to ship. Temu processed the order and took money from my credit card, WITHOUT MY AUTHORIZATION. I saw that on opening my banking app to see what was going on. How was that even possible????????? they even saved my ccv number!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! As a matter of fact, when I originally used my credit card for purchases on their site, I was asked if I wanted to save my credit card details on their system for future use - I DECLINED. I NEVER save my details on any site. I went to check and low and behold; my details have been saved. HOW SAFE AND TRUSTWORTHY ARE THEY????????
