Experian Credit Reporting indicates I signed up in -/-/-, which is true. However, I put in a request for cancellation in -/-/-. Experian says they received no notice of this and I have no confirmation email. I have asked them to examine their records for any logins to the site, and only requested credit back of $21.00 for the past 3 months, as that is standard to request for any purchase you dispute. They declined, offering 1 month credit only. I wish to receive the other two months. I should receive 6 months, but since I did not follow through on this - due to the death of my sister -/-/-, when I no longer was interested in following my credit score or anything else, this is all I am asking.
