I just called my cell provider. They indicated to me that I could get an app called extreme call blocker on my cell phone to eliminate these cruiseline calls. I have 5 different numbers for these advertising calls. I also just registered my cell number on our National Do Not Call List registry. It takes approx. 31 days. If I continue to get these calls after 31 days, this company (based out of the US) can still be find heavily by the CRTC.
Most cellular phones nowaday have the capability to reject calls from a list you define.
It is a very common feature. Usually there is a reject list, and reject call setting.
You'll need to add the numbers you want to block to the list, and enable the Call reject mode.
Play around the setting menus in your cellular phone. Good luck.
