Glitched account balance after refunds and non-existent customer support!

I am extremely frustrated with Payflex! I received two official emails from Payflex confirming that refunds were successfully processed for two different orders. While the individual order screens on my app show the correction, the main total account balance has NOT updated. It is still showing that I owe the full original amount before the refunds. This is a massive system glitch, and if it isn't fixed, your automated system is going to wrongfully debit my bank card for money I do not owe. To make matters worse, your customer service is completely non-existent. I emailed support only to be told it's closed. I submitted multiple tickets through your online portal over a week ago and have been completely ignored. I even resorted to inboxing your Facebook and Instagram pages, only to receive generic automated bot responses telling me to use the support channel that nobody answers. Logins via your email links are also failing, saying my password is incorrect, though I can log into the app fine. There is absolutely no human way to reach anyone. Because your team is completely unreachable and I have exhausted every single effort to get hold of a human being, I have been forced to freeze and block my bank card. I will not allow your glitched system to wrongfully debit my account for funds you have already acknowledged I do not owe. Please have a senior technician or manager manually rebuild my account profile balance to reflect the true amount before an automated debit occurs.
