Yes it is calling us as well. It started yesterday June 2 and it is still going on today. Yesterday they where 1/2 an hour apart or so, today it started at 11:30 and has been calling every 5 minutes or so for an hour and a half. If you answer you get a beep every second or so (not the fax machine squeal. When you call back you get TD Monnex, we have called several times and talked to several people with no results, not sure they know how to deal with the problem. Going to have to send them the long distance bill!
Not sure what to do next, but will keep trying.
