STOP CALLING I DONT NEED THE SERVICE

They keep calling and I have told them that I am not in need of their services. I think they are a debt counseling company but pretend to be a company that can help me with my overcharges or something like that. What i hate about them is I always get an sms that says I gave consent for them to request my credit report, which I did not do. I have called their office and asked them to remove me off their data base because I unfortunately do not trust this service. I called until they hung up on me and now they not taking my calls.
