I receive calls from this number saying they want to work with me in reducing my credit card interest rates.  The recorded message first told me that someone has been unsuccessfully trying to reach me.  Once a live agent came on she claimed that I had been receiving informational mailings from Credit Services regarding their services.  I have received no such mailings.  They claim not to be a credit repair service, they only work with credit card companies to reduce rates.  Has anyone utilized this service??
