There are numerous reports on the Internet about these calls, which appear to be a twist on the medical alert scam. Callers are asked to press numbers and are asked for personal information that could be used for ID theft. The callers may also try to deceive consumers into thinking they will receive a free medical alert device, when in fact the device comes with a monthly fee.
Though the amount of groceries differs in this case, it appears to be similar to the scam calls being reported by Western Virginia BBB in August.
BBB advises you to hang up if you receive such a call.
