Refund of purchase no response from Customer care

My husband purchased a Guess watch on his return trip via Emirates airlines, unfortunately the watch was too big for my wrist and so I returned the watch at the Emirates Umhlanga office, to date almost three months down the line I have had no communication on a refund. All communications are done via mail and there seems to be no response to my numerous mails. I have lost my patience with Emirates and hence seek your assistance.
