Ajio — Trying to return a dress from last two months

Have been trying to return a dress from last two months. Not sure whats taking so long for Ajio to just arrange a return pickup?? Every-time customer service representative give some information, some excuse and a new date to be resolved. The complaint then gets closed in two days without resolving the issue.
The order id is FN[protected]. Have been following through email and phone but in vain.
