Unable to access payflex account in order to make payment and interested has been added to my account.

I am unable to access my account to make a payment. When I try to reset my password, I receive a message saying my email is not found. I requested assistance a week ago but have not received any response. Please contact me urgently, as I am already being charged interest. I have tried multiple channels to reach Payflex without success, and it is extremely frustrating to keep receiving SMS notifications that more interest has been added to my account. please contact me *** or ***
