If you call the number back, and choose option3, you can be added to their Do Not Call list. Also, they are likely calling to update your billing information. In my case, I had to cancel the credit card that the AllState MotorClub was billing to, so they were looking for a new method of payment.
They keep calling asking me to update my credit card info as it is no longer valid. Contacted All State as my account is up to date and no problems with my CC. These calls come almost daily... and never stop !
