LT Online Store — Non Delivery of Item

I ordered Kaspersky Total Security 2 Users 3 Years antivirus software from LT online store on 16 February 21 and made online payment of Rs 2348/- for the same. The order was confirmed by the Firm against order number 259718 and delivery within
8 days was assured.

After 16 days of placing the order I have neither received the item and nor has my money been refund. I tried many times to speak to the customer support of the Firm however their telephone numbers are not reachable. I also sent repeated mails on the email ID of the firm however no response has been received from them.

I would like the Firm to refund my money immediately.
