The American Association of Retired Persons, aka AARP, maintains an easy-to-remember toll-free phone number: OUR-AARP = 687-2277. Ah, yes, you do need to remember *which* toll-free 8xx AC to prefix before OUR-AARP -- is that to be 1-800? 1-855? 1-866? 1-877? 1-888? Or do they all work?
[The answer is that] only 1-888 is correct. The others (all but one, anyway) either
(i) Thank you for calling and warn you to pay close attention because their "menu options have changed", or
(ii) Congratulate you for having just won ... [sort of "prize" irrelevant] ... . (The one outlier is unclaimed and still up for grabs, according to the toll-free number merchant offering it to the errant caller -- or was so when last I called it.)
No rules in place to prevent this sort of blatant exploitation of innocent mistakes, I guess? All is "caveat emptor" and "bamboozle the unwary"?
(Sigh!) Cheers, -- tlvp
