The Souled Store — Pickup for exchange available at my pin code but not for Return

Address:

I ordered around 21 items from souled store. However some items were no as per my expectation and not of good quality fabric. Some were good but there were fitting issues. However to my surprise when i initiated Exchange it was accepted and pickup time was confirmed. However when I clicked for return in case of some items it is saying your pin code is not servicable.
Is it that the company does not want returns or is it a technical glitch. Whatever it is ... not expected.
