Whaaky. Com - order cancellation and refund

My self Adarsh Shukla and i have mistakenly ordered * MI *****mAh Power Banks from whaaky.com of rupees ***/- on due date **/**/**** at **:**:** AM, order number **********. i prepaid the money by debit card during ordering the product.
When i informed about this through email to whaaky.com, they haven't replied me about cancelling my order, haven, t called me. whaaky.com dindn.t refund the money also till date.
I thought whaaky.com is a fake company because on its helpline number no one pick up the phone, always only the rings goes and continously repeationg "transferring your call to the operator" .

Dear whaaky.com company if you are a genuie company then please call me or inform me and do the remedy of my issue.
