Take my number off your system!

I have never taken out a loan or financing of any kind with this company however I am bombarded with messages regarding payment of financing and threats of legal action for late/non payment. I have called multiple times to have my number removed from their system and yet they refuse to do so. This has been very traumatic for me as I was under the impression that I was a victim of identity theft. You need to manage your client information systems more effectively, this is nonsense!
