This number called and the same name, Dolphin Duct, came up. I ignored it and then called back to see if I could get an option to be removed from their call list. No one answered and there was no answering machine. Irritating! Also, this is a 905 number and I'm a 613 area code, not very close.

Got a call from this number around supper time.  Very odd as there is not a Dolphin Duct Cleaning in our vicinity (2 hour drive).  Told caller we were not interested.
