Enjoy getting Spam calls multiple times each day

I don't even have business with them, but they are as annoying as hell. I enjoy receiving multiple spam calls from them or their dependent companies each day for offers. Multiple requests to have me removed from their call lists result in nothing other than a reprieve for a day or so. Then the spam calling commences again. It is interesting that certain laws state that if opting out was done then it must be done. Not with this company.
