Complaint Review: MJR Collection Agency

I had owed money to a College that I went to. I called the College and told them I wanted to come in to pay.
That's when some moron at the school told me that I have to pay it to MJR instead, oppose to paying them directly in full, kinda my fault for following his advice. So I payed it in full to MJR in February
now it's July going on August I received no letter showing that I payed, It's still on my credit. I've emailed the whole school administration and MJR (voicemail is always full with complaints) I have received no reply from the School or MJR so now I'm going to go in person to MJR and the school. Bottom line never pay MJR a penny. Pay who you owe directly and tell MJR that you are going to pay your creditor directly. They will make up some lie about you being in there system even after you pay the company you owe directly.
Don't listen to them.
