Question for the ones that know.....maybe.

My wife was approved for full SSDI+medicare last Nov. 2, 3.5 years of backpay etc. Last week her lawyer received her cut. Last week SS told my wife her monthly check will be deposit in her account yesterday (Wednesday). This did not happen. They then told me on the phone that the monthly deposit will take place at the end of the month next month.....December's payment is deposited in January etc. Later in the day it dawned me what ever happened to November's payment? They only referred to December's not November's. Am I missing something here?
