This is a car warranty scam, and they use multiple phone numbers (caller IDs) to try to get through any "blocked calls" you've programmed into your phone system!  They also use the following numbers...
203-204-2992
954-601-2600
314-764-3303
314-764-3302

No doubt, there are other numbers they are using, but these are the ones I've blocked so far!  The problem is that they have gotten my cell phone number, so these ignorant ba$tard$ are now calling my cell phone.  Completely unacceptable!!!
