After paying monthly bills, 10 months later, Comed sent a bill for over $1, 000.00. Comed said the original bills were estimate bills and were mistakes, after long conversion with ComEd rude personnel, unreturn calls, incorrect information placed on account, re-adjusted incorrect billing. But I started paying the current monthly balance and extra 100.00 on prevoius balance. But this month wasn't able to sent payment by due date. So, a disconnect bill shows up for entire balance of 700.00. So, I called ComEd 8/16 to state I didn't have all that money at once, and informed the Customer Service Rep that I would pay last month bill $170+ and $100. extra for past on Friday 8/20. She stated that I needed to pay today$290.00+, and be placed on payment plan. After informing her that I didn't have it, and I would have it by Friday, and since I've been paying extra 100.00 monthly. Her response was that I can't set up what I want to pay, and that I should a payment plan on past due of $85.00 along with current. But I have been paying $100.00, which is 15.00 more than payment plan. Also, she stated that the balance was $1195.00 which included new bill of 298.+ and previous. After more than 40 minutes of rude conversion with Com Ed rep and 30 minutes holding before I even got her. I expressed that she was rude, and I would like to speak with Supervisor, her response was why?, they would tell me the same things. I still insisted that I speak with supervisor or collection dept, to state that I would pay this Friday 8/20. Finally, she stated that she would put in a request for supervisor to call back and it would take over 1-3 day and service will be disconneted and with 690 calls on hold. I informed her that I don't have the money and I will paid Friday, after explaining that my husband is out of work. After all that, I really wanted to tell her that if Com Ed would treat their customer better that 690 people wouldn't be on hold.
