Please find attachments in this form.

Problem Description:
I have ordered one product from 'Club Factory'.
I have ordered 'Medium' size night suit but received 'XXL', so i returned the product as suggested by their support team to the address shared by them(PFA).

Their team told me that they will refund the courier amount also if they found their mistake, which is already clear that they have delivered wrong size product so they should refund courier charges also.

When i had a word with their team on[protected] on app, they told me that they have received the product on warehouse and shared the screenshot also(PFA) in which it is mentioned that product has delivered to their warehouse in Gurgaon on[protected] at 7:00 pm, they said they will check the product once and will initiate the refund as soon as possible for both(order+courier charge).

Yesterday and today i again tried to connect with them, now they are saying that they haven't received the product in their warehouse yet, even when i have shared the screenshot with them.

Again & Again they are saying that 'we have raised your concern to the team, please contact us after 2-3 days' and whenever i contact to them they use to say the same thing at the end.

Desirable Resolution:
I want my money back (Order amount + Courier charges) either in my original source of payment (bank) or in club factory app.
