I have placed an order (15968068729060854A) on 7 Aug and the amount was also deducted from Rs. 3787.64.

Delivery should be on 10aug as per the status given on App. But I have not received it.
On 11 Aug I raised a complaint and his name was Mr. Mayank and he said that he has raised my complaint and the same will be resolve within 48 hours.
Now today on 12 Aug I have called on your customer no again and the agent name Priti said that the previous complaint was closed without any resolution.

Now she said that the senior team will contact me but till now i have not received any call. I have not received my order yet and as discussed with Ankit Pandey on 16 Aug, he assured me that i will receive a refund of my order within 48 hours but till now i have not received a refund.  Then on 19-Aug, again called on your customer care number and Sonu picked call, he assured me that I will receive a refund within 24 hours. but today is 21st and to date I have not received any refund.
Can you please check and help me out because its over 14 days when i have not received any resolution.
