This is easily one of the most frequent unwanted callers that I get on my home telephone line. I have answered on occasion and wound up speaking to someone who is obviously in a call centre overseas. I have called them back at this number and had a person - who's obviously overseas - claim that she's here in Edmonton (11728 Kingsway Avenue).
I have found that the call display information varies - sometimes the display name shows "Alberta"; other times it shows "Internat'l Call".
I have asked them to stop calling me. They continue to do so.
