It is Amazon Prime! They just delivered to my home this evening (though I was out at dinner). It was nice to have my package on the porch, waiting for me.
Celtic, you may be right, but in this case, it was Amazon Prime. (I wasn't sure myself, so when I noticed this missed call I googled the number. It coincided with my Amazon delivery, and realized this particular number is from Amazon.)
As did I Nic, I'm just saying for everyone else that if they're not sure about it to find another Amazon number and check. I wasn't dissing your post, just making a point that these sleezeballs DO do this
