I purchased Kenstar Cooler from Vijay Sales on 24/4/2022 through its App.
The price quoted was Rs. 4, 890.
I paid Rs.4, 890 and booked the cooler.
Vijay Sales delivered a different model of Kenstar Cooler to me. The price of that model is Rs. 4, 500.
I received a call from Vijay Sales +[protected] on 28/4/2022. The caller agreed that Vijay Sales has delivered a different product to me. The caller stated that he would issue a refund of the excess amount of Rs. 390.
I have not received the refund yet.
I tried to resolve it directly with Vijay Sales by sending emails to [protected]@vijaysales.com and [protected]@vijaysales.com. However, I only got Ticket Numbers, [protected] and [protected].
They keep asking for additional time.
I don't understand this; I gave them proof of amount paid by me and the invoice generated by them. It clearly proves that Vijay Sales has charged Rs.390 in excess to me. Still they are not refunding my money to me.
Please look into it.
