(CNN) - The Better Business Bureau is warning of a scam in which con artists impersonating cable company reps claim to offer you a great deal on your service.
Here's how it works:
You get an unsolicited call offering a special promotion on your cable bill. The caller claims if you pay upfront for a few months, you will get a discounted monthly rate.
You are then asked to buy pre-paid debit cards to make the up-front payment.
The Better Business Bureau recommends being cautious when answering unsolicited calls or emails and verifying the identity of someone who shows up at your doorstep.
Also, when in doubt, verify special deals with your cable company and never make payments with prepaid debit cards or wire transfers.
