On 16/02/2016, I had placed an order for four assignment materials costing Rs. 150 each ( *4= Rs.600/-), which was paid through SBI fund transfer in the name of Mr. Ashutosh Burman on the 17/02/2016.
I received details of the transaction on the 16/02/2016 from the company's whatsapp no +[protected] after which (17/02/2016) I had sent a copy of the transaction details on the same number. The picture of the receipt was delivered, downloaded and even seen, but to no response. All of my messages, after the picture, were delivered but never read. I had requested for initiation on refund but neither is there any sign or interest in replying, nor is there any one to answer the innumerable calls I've made.
It is going to be a month that I had placed the order and according to "the" abhaolutions advertisement, they wither send a hard copy which are to delivered within a week or send it in pdf format within 48 hours of order. I have been their customer once before this and i did not have any such issues.
