Thanks so much for all the additional information.
I am honestly stumped as to what might be happening with your benefit payment. What you are telling me goes contrary to social security rules. Since May 1977 all social security retirement beneficiaries have been scheduled to be paid on the second, third or fourth Wednesday of each month depending on the date of their birth. People receiving benefits before 1997 receive them on the 3rd of each month.
No one is scheduled to receive their benefit on the 15th of a month. Here is a link to the social security site that sets out the payment date for everyone receiving social security benefits, as well as for people receiving SSI benefits: https://www.ssa.gov/pubs/EN-05-10031.pdf
Based on your date of birth, and when you first began receiving your benefits, your benefits should be being deposited to your bank on or about the 3rd Wednesday of every month. No, the 3rd Wednesday is sometimes on the 15th, but more often than not, it is later in the month.
All I can suggest is that you call social security to try and unravel this issue you have. Their number is 1-***-***-****. But I can assure you that social security has never paid a benefit to any class of retiree the 15th of every month.
