Stop sending me blank credit courtesy checks
A handy way to stop those blank checks coming in the mail:
I called the company(not the main customer service number as I did not want to close the account but a number I was transferred to) and told them in a very disgusted voice that the person didn't live at this address and if my landlord saw the mail I would be evicted.
I lie all the time to corporations, it's the only way to deal with them. I did opt out years ago from solicitations but that does not prevent these checks from being issued.
