FlexPay Denied Orders & Took it out Of My account

I went to order Apple AirPods off of HSN through FlexPay. The first time I was told my card wasn’t accepted & was charged $53.53, I wanted to try again because it was a cashapp card & I was told to use my bank card, went & you my bank card and HSN cancelled my order & STILL TOOK $53.53, so overall they have taken around $107. I’m so upset!!!! I will NEVER order from this company.
