I've gotten three calls from them, each time I answer it gives me a "beep, beep, beep." I too just adopted a pet with a microchip, two weeks ago. Don't know exactly how to get them to stop calling.
Just got a call from this number on my personal mobile phone. Answered it, heard silence for a second or two and then a busy signal. Must be some kind of broken autodialing system.
ah Hah! its from microchipping... and pet insurance, i looked it up some more and if you aopt a pet from the humane society (like i just did) or any place that gives you pet insurance or microchipping well, then your number registers with them. im not so mad anymore but the calls are annoying when no one answers and u just get the busy signal. anyways, if you get this phone call you most likely adopted or microchipped a pet recently. i am going to the humane soc today to pick up my new friend, i'll be sure to pass this on to them lol
