CemAir Refund ?????

CemAir was grounded in December 2018. I requested refund 14 December was told it was in a ‘refund queue- 6 -8 weeks for processing. Numerous emails later still no refund. Worse still no response to last emails sent to CemAir. It’s now going for 6 to 8 months . Disgusting service. Disregard for passengers who pay a premium for flights to smaller airports.
