"Definition: Slamming occurs when your telephone service is switched from your current company to another one without your permission. Long-distance service is the most common target of slamming, but it can also happen with local or local-toll service."
Its apparently pretty common in the US but not quite as bad in Canada.
I'm furious. After almost 30 yrs of dialing the same number that I call almost weekly - there is a very large likelihood I will never be able to call that number again! The person who had that number doesn't feel any better than I do.
If you find yourself a victim of this - some of your actions should include....
- Phone your chosen carrier (the one you were with) advise them that you have been slammed. (on this - 99% of the time their front line people will not have a clue what the devil you are talking about - explain and move on up the chain - keep on moving up the chain until you get an answer from someone who does - my suggestion keep moving on up through the supervisor ranks till you are satisfied.)
- Phone the CRTC (in Canada) or the FCC (in the US) and launch a complaint
