Rent-A-Center review: payments/ agreement/ entering home with minors

Today I experience an awful and illegal situation with Rent a Center. First off I been a customer with them since 2011, done paid more than need to for whole furniture, entertainment and TVs from them. I talked to the Manager Pam last week and paid off my couch, I also am paying on a TV. I was some weeks behind but after discussing with manager she told me that I had to pay $50 which would be due today. I left the house to make a errands run which I left my 13, 12 and 11 yr old home. I get a call from my oldest stating that a guy from Rent a Center came in the house telling him that a payment needs to made. How dare he enter my home with minors talking to a child about Payments and proceeded to dismount the TV. I told my son to put the guy on the phone and asked him to leave because he had no right to enter the home with minors and he proceeded to say that he is taking the TV. I told him again to leave the house because its illegal and trust passing and I'm calling the Police. He left and I called the Bolingbrook rent a center and asked for the manager. She said she immediately told him to leave because at that point she knew he was wrong. I said I just talked to you last week and you told me my 50 payment was due on today, how is it that you sending somebody out to my house to pick up the TV and secondly him entering the home with no adults present and questioning a minor about payments. This was wrong on so many levels, my kids even though they was not suppose to open the door for nobody even if they did as rent a center policy and being the adult in the situation he was not supposed to enter the home. Now my kids are terrified, upset and sad that they did open the door and something bad could have happened to them. I WILL NEVER NEVER DO BUSINESS WITH THEM EVER AGAIN OR EVEN REFER ANY ONE TO THEM AGAIN. I will be returning the TV because dealing with this situation has made me so ANGER and DISAPPOINTED in their policy and rules of payments and my agreement. I will be taken legal actions as this was definitely illegal and against their policy and agreement.
