No Response and No Refunds!

What a Disappointment! A months ago I booked the tickets to Greyhound via Mosselbay, which it is on next week. And 5 days ago I got news the events had canceled due Corono Virus. I called to Greyhound service to cancel the tickets and refunds. They said I must email to refunds. So I emailed on same day, no responds or no feedback from them. Been a days until today, still no news from them and nothing refunds my monies. They have read on email but no responds? Bigger disappointment EVER!
