Amazon woes

I have probably defended Amazon in the past on the basis that a) it is an excellent, cheap and efficient source of books and b) it allows me to sell my own books through it, also relatively cheaply and easily.
 
But now, I feel like I am trapped in a Kafkaesque nightmare where the same things keep happening over and over again. It started two days ago, when I noticed that my book Murder in the Red Barnshows on the Amazon listing as “Currently unavailable, we don’t know when or if this item will be back in stock.” Hmm. I check my inventory status on Amazon, plenty of stock… Hmm. After about half an hour I manage to navigate through the tortuous system that is the Amazon “help” procedure, and send them an appropriate message. Twelve hours later, the answer comes back, the account has been suspended because I have not validated my bank account – the account where funds from sales via Amazon are sent.
 
Except that getting that information took three messages from me and three from Amazon; each one was from a different person, thanking me for taking the time to contact them and wishing me a wonderful day. I have pointed out to them that I have never had this request from them, and it seems rather strange commercial practise to suspend my account when someone at Amazon has not only forgotten to send me a message, but has failed to warn me of the impending suspension of my account.
 
And this morning, the same message is repeated. I suspect I am in contact with a Siri or Alexa…
