Nelson Watson & Associates rude calls constatly Haverhill, Massachusetts

THIS COMPANY HAS A CAPITAL ONE ACCOUNT IN MY MINOR SONS NAME AND THEY CALL ALL THE TIME AND I TOLD THEM HE WAS A MINOR AND THEY HAVE REPORTED IT TO ALL TO THE CREDIT BUREAUS AND HE DID NOTHING WRONG AND HE TURNS 18 IN MAY AND WANTS TO BUILD CREDIT AND THIS COMPANY HAS DONE THIS TO HIM.  SO I CALLED CAPITAL ONE AND THEY HAVE NO ACCOUNT IN HIS NAME. THEY SAID CAPITAL ONE WOULDNT KNOW BECAUSE THEY BOUGHT IT OUT AND THE LADY IN THE FRAUD DEPT. LOOKED INTO DIFFERENT SYSTEMS AND THEY WOULD NO IF IT WAS SENT TO THEM AND IT NEVER WAS BY CAPITAL ONE. ,NOW NELSON,WATSON HAS RUINED MY MINOR SONS CREDIT WHEN HE NEVER APPLIED FOR A CREDIT CARD WHEN HE WAS 12 YEARS OLD. THE ACCOUNT IS FROM MAY OF 2007. DOES ANYONE HAVE ANY COMMENTS OR SUGGESTIONS,IF SO IT WOULD BE GREATLY APPRECIATED.
