Sirius XM Sirius XM will not pay me my refund! They also caused Identify Theft and won't do anything about it! New York New York

I sold my car in February of this year so I canceled my service.  I was to receive a $99 refund. Sirius Listener Care had my old address in their system, so, as part of the request, I gave them my new address and asked them to send the check there.  Months went by...no check.  After several follow-up calls, I found out that the check had been mailed.  I asked for an image of the check.  When it arrived, it showed that the check was mailed to my old residence, and not my new one as requested.  Also, I saw that the check had been signed and deposited into a Bank of America account (I do business with Wells Fargo).  In summary, Sirius did mail the check, but it was not mailed to the correct address.  Someone stole the check and fraudulently deposited it into their own account.
