house foreclosed 3 weeks ago, just found out

I was 5 months behind on my mortgage. I just found out that my home was auctioned back to the bank on June 3rd. In Missouri the right of redemption only comes into play if you give advanced notice, so that doesn't help me at all. I spoke to an attorney who advised me to make sure the notices went into a county paper properly, which they did. The certified "notice of sale" was never delivered to me, I remember the rural postal carrier leaving a "sign here for delivery" slip in my box in early May, which I signed, but no certified letter was delivered.
Has anyone ever successfully had a mortgage company agree to a "recision of foreclosure", and if so, under what conditions?
Please someone give me advice, the attorney said there was nothing that could be done, but I am so shocked that this could happen.

The lender should formally inform you about the foreclosure before taking any such steps. I don't think it is legal for the lender to foreclose the property before informing you. I will suggest you to contact some other lawyer and take his help in this regard. He will let you know whether or not you can take any legal actions against your lender.

Since it sounds like an attempt was made to notify you, I would be looking at the post office for an explaination as to why didnt receive your certified mail. Maybe you can get proof from them, that it was in fact not delivered....I would be talking to your local postmaster general. However, being that you knew you where behind in your mortgage, you do take some of the blame for not following up on that letter.
