I want to submit a complaint against amazon.com. I ordered seagate backup plus slim 1tb portable external hard drive with 200gb of cloud storage on 26 october 2016. Cost of this product was 3797 inr on that time. I paid same amount in advance. But after 15 days when i called to complaint regarding i do not receive my hardisk then they assured me that your product will reach as soon as possible. After 40 days from order i did not get my hardisk. During this period i called 5 to 6 times at amazon customer care. Each time they assured me we will deliver you hardisk.
But they cancelled my order without my information & refund my amount after 2 months. Now cost of same product is apprx. 4500 inr.
They used my money two months with out delivery of my product & cost of same product has hiked by apprx. 700 inr.
I would request you please do justice with me. My ordered mail id is [protected]@gmail.com
If you require additional information you can mail me at [protected]@gmail.com.
