Asus India — Wrong product delivered, No Reverse Pickup, No Refund

Bought Zephyrus G14 & added ROG Gladius lll mouse from asusrpomo website but received ROG Strix Impact mouse instead.
Raised concern on 6th Sept. & was informed that they didn't have the correct item in stock so they sent another mouse.
I confirmed that i don't need the alternate mouse as it of lesser value that what i ordered.
Asuspromo support confirmed on the same day 6th Sept. that reverse pickup will be arranged followed by a refund.
I have done multiple emails, calls but still waiting since a month just for reverse pickup.
