GA real estate and foreclosure law

My husband was hurt in a motorcycle accident, not his fault, but we have been waiting for over 4 months for the insurance companies to settle. He is not able to work and we have only my income coming in to meet all financial requirements. I was intially told by my mortgage company that they would let us go three months without payment and add that amount to the end of the loan. Three weeks ago I found out that they denied this option (without letting me know) and I owed three months. Two weeks ago I received a letter of intent to foreclose and today we received a lawyers letter that they were advertising the house to be sold the first week in November unless we paid the entire loan off within 10 days. I filled out another request for help to the mortgages companies loss mitigation unit. Yesterday I received mail from them saying it they would look into my request and it could be another 30 days before I heard anything. They advised it wouldn't stop any foreclosure in the meantime. We are being hounded daily with calls from creditors, hospitals, doctors, car loans, etc. The insurance company didn't pay off my husbands totalled motorcylce. They paid $15,000 and we owe $1300 yet. They call us at least 10 times a day wanting payment. They can't understand he has NO money coming in. Is there any way we can save our home and stop these harrassing calls?
