Poor Service from AA (Mechanical Warranties division)

I have made numerous calls to AA Mechanical Warranties to cancel a policy on a vehicle that was sold a month ago. If one gets through to a person, the agent just transfers the call to a different department that is supposed to assist with the cancellation. The agent taking the call just informs that she has to transfer the call to retentions (Who by the way, never picks up the telephone. ) This happened 3 times already. I have sent emails to the complaints department as well as to their Info e-mail address, still to no avail. They promise to call back, but that does also not happen. Their call back option does not seem to work, as I have also tried that route (to request a call back. ) Yet they keep on deducting the premium. With that there is no system issues. I am sick and tired of them. I a paying for a service that I do not receive. Wish they show the same enthusiasm with cancellations as they do when they haunt one to sell a policy. Pathetic!
