sorry you had so many issues, but any calls you get are only after your account is already 31+ days past due to assist you. Any phone # they leave is direct to reach a live account representative person, not any computer system. there may be a hold time during peak calling times or days, but usually it's less than a few minutes but calling late night is often a great idea for prompt service.
to make online payments (with no fee) go to www.FIACardServices.com or if you are polite and professional they will do a check payment by phone and waive the processing fee (again, be polite and professional when you ask), OR you can do a Bill-Pay to your credit card acct from your own checking account online from your bank or credit union (you need to know when this payment is expected to post to your credit card account as some banks print a physical check and mail it to your credit card company which will of course cause a delay in receiving and processing). as with any transaction, follow-up to be sure it was accurately completed.
at www.FIACardServices.com you can get up-to-the-minute account activity (including pending transactions not yet posted), make payments, view and download statements, and complete address changes.
typically these companies invest in technology to make things quicker and simpler...if you are late and they have to start calling you that raises their expenses in servicing your account, in addition they then have to set aside extra reserves toward bad debt based upon your increased risk assessment. they don't spend money on systems to annoy you, they just simply want you to pay what you owe them on time.
