Ajio — I haven't received the product I had ordered but got notification that my product was delivered.

Dear Sir,
I had ordered a kurta set on 21/9/21 and made an UPI payment for it. On 28/9/21 I got a message that my product was delivered, but it did not get delivered at my address. Even the notifications in Ajio app shows that the item was delivered which was actually false. I had contacted the customer care service team but to my dismay my call was hung up by two persons respectively for a long time and eventually disconnected my call. Lastly a person attended to my call and he lodged a complaint. Also the complaint was supposed to be resolved by 5/10/21. But till now I haven't got any solution. I had again tried contacting the customer service team but no one attended to my call even after repeated attempts of dialling. I then get a mail that they require two more business days for this. This is totally harrasment to me. I have already paid the full amount through UPI but still neither got the refund nor the product. Kindly do the needful at your end.
Regards
