Unable to Contact Payflex Regarding Incorrect Arrears

I am extremely frustrated with the lack of customer service from payflex.co.za⁠�. My account was paid up last year, yet I am now being told that the account is in arrears, which makes absolutely no sense. I have been trying to get clarity on this matter, but it is almost impossible to contact anyone for assistance. As a customer, I expect: proper communication, access to account information, and an explanation before being told I owe money. It is very stressful dealing with a company that cannot be reached when there is a dispute on the account. I urgently need someone to investigate this matter properly and provide a full breakdown of the alleged outstanding amount. I hope this issue can be resolved as soon as possible.
