Every single day for the last 2 weeks, including weekends without fail. Yesterday has jumped to 2 calls a day.
On the 2 occasions when I decided to actually answer the call, my line terminated within 3 seconds. I'm going to try calling Rogers (the best assumption yet for a culprit) and have myself removed from their mailing lists. Will update with an outcome, if there is one.....
I saw GasMan's posting so I called Atelka and asked to be put on the no call list. We will see what happens. They have been calling 5 times a day lately. They didn't ask any questions, just got my number and apologized for the inconvenience.
