accessing my account

I have called many many times about getting my account that was under my ex-wife's name to mine.  The bill is being done by auto pay and has been fine.  I am switching bank accounts and I have not been able to access my account as they say I don't have one.  Hmm.  Been paying for Direct TV at the current home for years now.  All I want is to be able to access my account so I can make sure you continue to be paid properly.  I hope this is something you would want.
