I'm Doug, and I'm very sorry to hear of your situation. My goal is to provide you with excellent service today. I have been a licensed attorney for more than 3 decades. Please don't confuse excellent service with a satisfactory outcome based on your wants and desires. I can only explain the law to you---not guarantee that you will be happy with the outcome---any more than a cancer surgeon can guarantee a cure.
What you are saying sounds about right in terms of your right to benefits. Under Social Security regulations, you cannot collect a benefit for the first 5 months of any period of disability. Your first month of disability pay would have been in July---but because benefits are paid one month after the benefit is earned, your July benefit was paid in August. Your benefits have been paid exactly as allowed under the law.
Had you been disabled say in October of last year and first applied for benefits in June of this year, then you could have received retroactive benefits after the first 5 months. But given that your disability began in February, you are not entitled to retroactive benefits to the date of disability because of the 5 month waiting time.
