Product: Debt collection

I submitted a request to investigate, and the company responded with a forged document. There was no condition to my employment that indicated a promissory note would be required for repayment of the licences ( all stated fully paid training and licensing ). I did not sign the note, and yet they have gone ahead and forged one after seeing I had not. The dates do not match the dates a promissory note would need for a test paid for XX/XX/XXXX and taken on XX/XX/XXXX - the date on the documents show XX/XX/XXXX ( more than a week from the payment date ). They had a legal team fail to suppress my  reporting of their actions, and in so made clear they did not have claim to the promissory note amount.
