Amazon review: I had a billing issue

My bill this month included a monthly fee for HBO MAX. I pay annual to HBO directly so I knew this was not a valid charge! First let me say, I love the convenience of Amazon but all of their self serve Customer Service issues are flawed. FIRST: I had to search the internet to get a phone #, they want you to use their automated service; Im OK with that! But the phone number to call gives you a choice of the last 3 items purchased and if your issue is not one of those the call cuts you off! Same with their chat service! After 5 failed attempts, I said I needed a representative to speak about one of my last 3 purchases, I ended up with a representative, probably in India who speaks too fast so I couldnt understand him. I finally got him to slow down and he did tell me that he would credit my account. There is no way for me to see if it really happened so I need to pay the bill and hope that the credit shows up next month. For Gods sake AMAZON, put a billing issue on your automated services!
