Just had chat with Amazon rep.
My prime membership is expiring soon, How can I renew ?
You are now connected to Amazon from Amazon.in
Amazon: Hello my name is Ujjal. I'll surely help you.
Me: Ujjal, How can I renew Prime ?
Amazon: I'll surely help you to renew Prime.
Me: thanks
Amazon: Please allow me a minute while I look into this.
Me: sure
Amazon: Thanks for waiting.
I have checked your account and I found your Prime membership will be expired on October 29, 2017
Unfortunately there is no way to renew before it expires. I would really appreciate if you wait till October 29, 2017
Further, if there is any update regarding promotion we'll let you via email.
Me: Ok , Thanks..
