How to return items mandala?

Excuse me, could you please clarify the process for returning items from Mandala? I've made a purchase through their platform but I'm not completely satisfied with the product. Are there any specific steps I need to follow to initiate a return? Are there any time limits for requesting a return, and are there any fees associated with it? Also, how will I be refunded for the returned item? Will it be through the same payment method I used for the original purchase? It would be greatly appreciated if you could provide me with a step-by-step guide on the return process at Mandala.
