Voltas — voltas 1.5 ton 5 star issue with sharptronics

Hi team, i have paid rs 45000 on jan 7th for voltas 1.5ton 5star ac on sharptronics porur chennai. Before booking they told it will be delivered on same day or by next day. As i paid on 7jan evening they told priduct deliver on 8th or by 9th thursday for sure. But on 9th tgey told the product delivery will be delayed for further two days. So i have cancled the order and asked them to refund. Shartronics asked my bank details to do neft transfer amount by 6pm on 10th. I did so. But till today 11th afternoon amount not refunded. I am totally disappointed by sharptronics and voltas. I am shareholder in voltas too and no re thinking to hold shares or not. Requesting to take action against sharptronics as it total upset for the customer.
