Slow/no communication on my refund.

I'm going through a frustrating process of waiting for my refund from Air Seychelles with slow/no responses from the airline. I purchased return tickets & the tickets were not issued. I was told that my money would be refunded within 3-5 business days. Today marks the 6th business day according to my calendar. If there was timely or even proper communication from the airline, then I'd be willing to understand. But having no form of communication is frustrating & an inconvenience.
