Credit card or prepaid card: Getting a credit card

I recently noticed several " hard inquiries '' on my credit report from financial institutions I did not apply for any credit from. A few days later I received written correspondence stating that they were processing my applications. I did not apply for any credit products from them! I attempted to contact all the companies at the phone numbers provided in the mailings and none of them were answered- just sent me to recorded message that all operators were busy and to try back again. The companies are : XXXX XXXX XXXX XXXX XXXX XXXX XXXX Capital One- this one sent me a credit card I will not be activating and I am worried that trying to cancel the card will negatively affect my credit report. I want the " hard inquires '' and any other information they report removed from my credit report as they are fraudulent! I want the Capital One card canceled and all information removed about it from my credit report. I attempted to file disputes with the three major credit reporting agencies and was unable to fine the link to actually file a dispute! All links just lead to information on disputes! The credit reporting companies must provide prominent links or actual phone numbers to the real dispute process.
