Minor update. Skip straight to the bottom if you just want to read the update.
Recap: I'm now 67 years and 7 months old. I was incorrectly WEP'ed from my 65th birthday, and at one point my SS was stopped completely (supposedly due to me not sending specific forms - although their track record on processing forms isn't great; hence this update).
it took almost a year to sort out the problem and refund the incorrectly WEP'ed amounts - by which time I was close to my 66th birthday ... at which time they didn't WEP me and still haven't WEP'ed me (now 19 months since my 66th birthday)!
In conversations with FBU (yes, they used to actually answer the phones occasionally), I was asked to send a PODSU 231 form, allowing FBU to receive information from DWP about my NICs background. In a follow-up call, they told me that DWP hadn't responded to the PODSU form and they'd try again. Eventually, I received confirmation that DWP had supplied the NICs information, at which time I figured they would soon WEP me. This was 8 months ago, since when I've been completely unable to reach FBU by phone.
In June this year (5 moths ago), I received Form 7162 from SSA Wilks-Barre with no cover letter or instructions, and I sent this by recorded delivery, signed-for service to FBU, as this is what they said I should do (not send it back to Wilks-Barre). Royal Mail tracking never showed it was received and I contacted FBU by secure message to ask for confirmation that they received the form 7162. They never responded.
In October this year I received a second Form 7162 (marked "second request") from Wilks Barre, again with no cover letter or instructions. I again completed and sent this to FBU recorded delivery, signed-for service (which supposedly takes 1-2 days) but as it wasn't showing as delivered one week later, I again contacted FBU by secure message to ask them to confirm receipt. They responded a few days later, "Due to the number of forms received and the way the scanned/uploaded into Social Security's records, we can't confirm receipt of form SSA-7162. If Social Security does not receive the form, a second form will be mailed to you.” This seems rather disingenuous - on past occasions when I did manage to reach a real person, they were able to access my records and see every form that had ever been received from me and uploaded.
Luckily, two days later Royal Mail confirmed signed-for delivery. So at least I now know FBU received the second form - though I can't be sure that they uploaded it to SSA.
My concern is that they seem so inefficient, and at the top of Form 7162 it states quite clearly that, "Failure to complete and return this form within 60 days will result in suspension of benefits". Who knows what will happen or what Trump will do about foreigners receiving benefits ... I just wonder what has happened in the past 6-12 months to make FBU so inefficient and unresponsive. It's ludicrous that their recorded message says FBU is not available to receive calls "at this time", and they occasionally post revised (and reduced) open hours for calls, when in fact they just never answer the phone, and haven't done since about February/March!
