Amazon.in — Technical Stuff and Not able to right information

Address:

Chennai, Tamil Nadu

I am totally Unsatisfied with Amazon customer care and Technical Stuff. I registered on 20th July for Yu Yureka Plus by this same mail id([protected]@gmail.com). I tried today by 11:30 AM and verified with customer care about my registration and availability and they verified and told about availability time by 11:50 AM. A tried by 11:50 AM to 12:05 PM every moment for add to cart and buy. But not able to Purchase. In While 11:50 AM to 12:10 PM i talked with 3-4 Customer care Person about not coming option to add item in cart and buy in my account, But all said your email id not registered and I was totally Stuck!!!, because just 15 min before they confirm about registration. And lastly one Customer care Person add yureka plus in my cart at 12:15 PM but that price was Rs.10999. again stuck!! bcoz Price is Rs.9999 only. So Just I want to know about Your Support and Technical Stuff. Please don't cheat with Customer.
