It was HBOMAX that billed $156.74, on the very same day that Apple charged $157.06. Technically, I did not initiate it, it simply appeared, without notice or email, I signed up on my iPhone, not on the internet at HBO's website. Although there was very good documentation, invoices, etc. for the February 1st charge from Apple (I found the older invoice in the MUSIC Store, by the way, that would have been good to know) and after pushing through the same advice at the first level of customer support (contact your provider, even though the provider is not the problem) got Specialist Support at HBOMAX. Was able to prove that I was indeed charged by them, without notification or invoice. Two different amounts, two different credit cards, two different vendors. Not easy to track down. Turns out HBOMAX had a typo in my email address, and had opened two separate accounts. It 's been elevated again, with a case number, and I have been promised a refund. Hope this helps the next Apple customer.
