Poor service

I have purchased a TP-Link TL-WR720N Wireless Router of Rs.754.00 from Amazon India online purchase.
Order Placed: 8 September 2014
Amazon.in order number: 402-8558881-3701940
I have nt still received d order, i have contacted several times of dat i have nt received d order, d delivery date was 13th Sept 14. Den they gave 22nd sept that will be delivered with in it, but still i did not got d order. I m very much upset with dis, d customer representative could make me know that d order is late n til wen it will b delivered. On 23rd i gave d customer helper to wether it will b delivered or nt or else to cancel my order, den he gave me 48 hrs d\that it will b delivered with in 48 hrs or else to contact n will return d amt back n today 48 hrs completed bt i have nt received it yet. so i contacted d Amazon customer representative n told them to cancel my order n to refund my full amt back. They have taken d request to cancel my order n to return d amt back.
As d amt will b refund, but i was to much harrased by all dis. Did nt expected dis type of service. I will reorder d product from any other seller, bt d days i have to b in it was to much to get d product.
