Account Blocked Without Explanation

I tried using Payflex to make a purchase on Wootware, but every time I attempt to check out, I’m redirected to Payflex and told my account is blocked. This is confusing because I’m a new user and have never used Payflex before.

When I log into my account through the app or website, everything works fine, and there’s no indication of any issue. I emailed Payflex support on 24 October 2024 to resolve this, but I haven’t received any response to date. i am still trying to purchase

This has been an incredibly frustrating experience, and the lack of customer support is unacceptable.
