Mytrip.com - no communication, no refund

During January this year I booked two tickets for flights from Namibia on behalf of a friend; however I made a mistake with the names. I proceeded to cancel those two tickets and promptly paid for a second set of two tickets.

Once the tickets were paid for I went about cancelling the first two tickets, and asked for a refund. We were refunded only one ticket - so I emailed the billing/accounts department explaining the situation so that I could get the refund completed (this is in February)

I have still not received the complete refund, and all communication with Mytrip.com has been met with silence.

I will not recommend Mytrip.com at all, and will actively discourage friends and colleagues from ever using Mytrip.com
