New professional here. I'm Doug, and I'm sorry to hear of the confusion. My goal is to provide you with excellent service today. I do understand what happened and can explain it fully to you.
If you took your social security benefit beginning in August of this year and you were older than 66 at the time, then you WILL get your benefit increase for each month that you waited after age 66. The monthly increase is 2/3% per month.
However, social security only calculates the delayed benefit increases annually, and so when you took your retirement in August, you would have been paid the delayed retirement increase only through the end of 2015---which resulted in a bit less of a monthly benefit. However, social security will make good on your delayed benefit increase.
This December when social security recalculates your benefit, the additional 7 or 8 months of 2015 will be added in and you will see your 2016 benefit increase by the approximate 5.3% that was missed when you first took your retirement in August. You will also get a lump sum check for the additional benefit that was not paid from January to August---which should amount to about $800 to $1,000.
So by this time next year your benefit payment will be more than $100 per month higher because you will have been given the 2015 increase for the 7 or 8 additional months you delayed retirement with your 2016 benefit schedule.
