It's unlikely that scams are ever going to disappear so it's important to be aware of possible scams and to be suspicious of unusual things.
Visit the Better Business Bureau Scam Tracker to see different areas and time periods. I'll be sharing common scams around Alberta this last year.
280+ scams were reported to BBB. Because these don't include any scams just reported to police, or ones that people didn't report period the "actual" number of people involved in a scam is actually much higher. Now, being involved in a scam doesn't necessarily mean that any money was lost. Some people recolonize the scam before anything or sometimes people are harassed but they don't fold.
Depending on the scam you may get your money back from your bank or credit card but not always. Even if you do get your money back there may be a delay in the refund and you might need that money. It's also possible that your name and info could be tarnished- "you" committed a crime, "you" ran up a credit card bill and refused to pay. Clearing your name can be challenging and time consuming.
Calling an Unknown Number
Not a BBB scam but important general knowledge. If you see a strange number on your phone or get a weird voice mail, don't call the number back. It may be a pay-per-call number that will charge you or someone's personal number could have been spoofed and the actual owners have no way of knowing what's going on.
It's also possible that there's more than one scammer working the phone so when you call the number they gave you for the credit card company a second person will pick up and say that they're legit and someone has been trying to contact you. Use contact numbers you all ready have or have easy access to.
