On 03 June 2019 I mailed you a check, 14821, in the amount of $ 200.65 to cover your charges on three DTE accounts from the Lincoln Park, MI US Post Office: [protected] [protected] [protected]. Those account numbers were clearly written on the check in its memo line. I received no billing for account [protected] by mail, but received a "DTE Energy Alert - Payment Due Reminder!" email from you telling me the amount due was $ 110.54 on 25 May 2019. I included the payment stubs from accounts [protected] and [protected], and stapled a 3" x 3" blue sticky note to both with the information on the [protected] payment. Had no payment stub for the [protected] payment since I never received a bill. You texted me several times on my phone and robocalled me several times after the payment was sent. Could not get anyone to reply when I answered your robocalls. Assumed you cashed my check and the calls were in error. You presented my check, 14821, to my bank on 19 June and it was honored. Don't understand why it was presented so late, but it may have been due to my stapling the sticky note to it, which was a deliberate attempt to get your payment processor's attention. Sixteen days seems wildly excessive. Was out of town from 13 June to 21 June. Received a shut off notice during that time in my mail which indicated that account [protected] was going to be shut off on 24 June. Called your toll free line on 22 June around 08:30 AM and finally got a real human being. Explained the situation but was told that the shut off would take place unless I paid $ 110.54 by credit card. I did so under protest. The woman (Cassandra?) who took my payment transferred me to a supervisor so I could protest, but the line went dead. Visited my bank this morning and had them print out the attached copy of cancelled check 14821. You people had already received and cashed my payment on 19 June, three days before you stood me up for a duplicate payment. I made that second payment on a debit card which draws on the checking account from which 14821 was drafted. The duplicate payment to you resulted in a $ 30 overdraft fee from my bank. I keep my balance lean due to several past identity thefts which have cost me dearly. I assumed you had not cashed check 14821 and the $ 110.54 would be in the account. Big mistake. Please determine what happened to the $ 110.54 originally sent you in check 14821. Then explain how you are going to reimburse me for the overdraft fee I just incurred. There is no excuse for this screw up on your part. You have my contact information.
