I just submitted my complaint yesterday, case # -. I went to the post office after dinner, there is a foreclosure notice from a law firm in NJ. I will try to attach it amd send it tonight. So I look to see when it was mailed, and there is no date on the letter. It is undated. Furthermore, we are told to respond within 20 days of the receipt of the letter. And it is undated? This getting worse by the hour. It is just a - page letter. No date.
