Amazon India — Unable to write book review

I have been trying to write review for the book, the first republic b, y venkatesh rangan. I have sent email complaints and spoken to your team members and still waiting for a reply for the past two months. I had ordered four copies of the book from your website. Every time i try to send my review, it appears in red letters that i cannot send a review from my account. When enquirer, i was told
1) i can only send from an email account. I have added email to my phone account. Still unsuccessful.
2) i should have spent at least rs.3000 for the account. I have spent more than rs 4000 in 2020.
3) was told should buy at least 13 products.
Why so many restrictions for writing a single book review?
Why do you ask for product reviews if you do not want to publish it?
What is the use of buying a book if a review cannot be written?
What is the connection between buying products and writing a book review?
Why do you want to harass a regular customer, a senior citizen, when all i ask is to write a review?
Do you want me to discontinue buying products from your website?
In the past i could write review for a kitchen product from amazon even though i had not bought for rs 3000. Why the restriction now?
Also i could easily write a book review in google book store, without any restrictions.
Please resolve my problem at the earliest, otherwise i will stop buying from amazon.in.
