I have received two calls from this number 905-963-9079 traced back to company "GT Group Telecom Services Corp."   I suspect this is not a bonafide company.  They say they want to combine credit possibly to get credit card number.  On both ocassions I aske to have my number removed from their list and was promptly disconnected.

Called me at 3 something in the morning and all I hear is someone saying
good morning over and over I say hello and all I hear being repeated is good morning so I hung up. I looked up the area code and it is someone calling for canada.
