how can i call to cancel a ticket

Need to call there Customer care number for cancellation.....The said number is available on there website

Call Customer Care

Google Greyhound, to find, a contact number. Greyhound, has a national booking line& the local stations, also have, private lines, that you, can call. I, don't know, if Greyhound tickets, are normally refundable, however, there, are exceptions-as per, my own experience. I, have had to cancel a Greyhound ticket before; I got a full, refund-quickly. Bayo

Just call and tell them to cut it

That's a good question when they don't answer the phone
