I've been having the same issue, getting calls from them every day which I do not answer.
If you call them back, press 1 for service in English, and then press 1 again to be added to the do not call list, you enter your number and should be good to go!

Called several times and didn't leave message. So annoying.

Called claiming they were from CIBC and then tried to get private information from me.  I said I didn't feel comfortable giving out any information to a random caller claiming to be my bank and ended the phonecall.  They still call frequently, though, never leaving messages.  They are b*****ds.

They call me everyday at ~10 AM. Usually silence at the other end.

I am fed up paying for a private number and getting this call 3 times a day.Will look into legal action if this does not stop immediately, I have a very sick person living here and it is interupting their life very negatively.

they call everyday around 10 in the morning and even on the weekend.
