Don't ever give your phone number to Clair Honda Service (West Roxbury, MA).
They (without any permission) put your number in a autodialer computer (even for cell phones), and call you repeatedly with "discount service offers" for years after a service visit.
Calling their employees, supervisors, or the FCC to remove your number has no effect on them as I doubt they even know how to remove a phone number from their autodial comptuers.
The phone calls come in from 800-815-9907, which is probably a third party vendor they outsource their advertising to.
