How Can I Get My Date Due For The Bill I Owe. I Am Retired And Get Paid Twice A

I Would Like To Get The Date Due Changed So I Am Not Making $35.00 Late Fees Each Month. I Get Harrissing Calls Each Month And I Am Sick Of Them. I Have Always Paid My Bills On Time And Never Have I Been Called For Payment.once I Am Able To Pay This Bill Off. I Will Never Do Business With You Again. Your Way Of Doiung Business Is Absured.i Have Sent Payments To You That Have Been Returned To Me. I Do All My Banking On Line So I Don;t Understand Why The Payments Aqre Being Returned To Me. As Far As Your Receiving Payment From Me In November 2912 Is Because They Are Returned. My Bank Has No Idea Why This Is Happening. Last Payment I Sent Of $58.00 On Feb. 27 Was Returned To Me In March.
