cancellation of subscription and login failure

Im disappointed to say the least, I have been paying Experian my monthly subscription to have access to my credit report for over two years now. I have failed to log onto my profile as I have changed my number and informed them that I need these reset to no avail. I would like to cancel my association with CREDIT EXPERT EXPERIAN as of immediate effect but im still not getting any feedback to my requests sent to them, neither can I get through on the customer line. if this perpetuates I would seek ways of getting my money back as measly as it is. its the ethics that they lack.!!!11
