All was going well as I was promised no or minimal principal loss until recently I was issued a "Non Performing Loan Reconciliation" where I lost over 60% of my principal with no interests earned for 5 years.I'm typically not an emotional person, but I was extremely depressed and infuriated when I saw this.
