It doesn't matter if you request your number to be removed, this bogus company will continue to call. It's a bunch of scum bags sitting in a low budget out house, making random calls in between calling their family members/sexual partners.
Someone needs to shut down these offices and pass serious laws with penalties. This is just as harassing as stalking.
