DITTO - automated call from costco canada for a food recall of a product we had indeed bought.
If you do not shop at Costco, it may be your number is on file for the previous user of that phone number. Alternately, it seems these may be coming out of a general call center (i.e Costco hires a company to do these) because some reports indicate other types of calls (or it's indeed a Costco number, but others are spoofing the caller id.)
Got a call on Nov 20, at around 7pm, our answering machine cut out because I picked up the phone. I heard a female voice talking about a restaurant ..., I simply hang up the phone (sorry, do not like useless calls). Then I checked the machine and heard the first sentence of the call, something about our Costco account "according to our record..." Checked the Net and found these postings about the phone number.
