Capital One Credit Card Complaint

Capital One Credit card department,

Customer service / Customer relations Massachusetts

Capital One is refusing to provide me with my old/last account number. I have spent hours of the phone getting transferred to different departments within Capital One and they said they are not allow to provide that information to me. I need this full number to access - - 's system in order to find an old receipt for a purchase I made using this card. Since it was a secondary card ( it was under my name and social security number, but used by my husband with his name on it -, it is not listed on the old account statements. Only my primary credit card number is listed on the statements.
