A former employer has stated I owe him money. However, according to my records I have paid this debt in full and in fact am owed money by this employer due to an overpayment. I requested a verification of debt and proof this money was still owed after my payments and my former employer provided only a copy of an invoice that he typed- no backup, no proof. I however provided a XXXX Page document showing that I do not owe this money and that is has been paid in full and that he owes me money. This is a civil matter between my former employer and myself. Only a court of law can determine if I owe him money or he owes me, not some third party collection company. Furthermore, a copy of a invoice with no backup is not a valid proof of debt - anyone can type an invoice. This collection co is also reporting to my credit as rental/leasing debt which will hamper my ability to rent a property. I do not owe a debt stemming from any sort of unpaid rents. My prior company is a XXXX. I do not owe any sort of rent to them which is what they are categorizing it as. I have called this company and mailed them a letter stating I dispute this debt. Their response is that the invoice copy is a valid proof of debt!!!
