Athene Alliance One Kept taking my money, but refuses to tell me where it is. Internet

Athene has been steadily withdrawing $181.58 from my bank account for years.  I have been calling for months trying to get any information regarding my annuity.  This is an annuity that was originally with Aviva.  Athene says they cannot provide the information since they have given the account to one of their "other branches", Alliance One. I Google'd Alliance One and it says it is a collection agency.  I asked Athene if Alliance One was in fact a collection agency and I was told no.  I was given a number to reach them and when I called the m they told me that the accounts were in transition and they would have to get the information from Athene.   I spent $30 and stopped payment on the Athene ACH withdrawals.  Someone is in possession of several thousand dollars belonging to me and neither Athene or Alliance One will provide me with any information!!
