Greyhound refusing to rebook or refund

I think you guys don't even deserve this 1 star, if there was something less I could rate I would have, ur service is pathetic to say the least.

I purchased a ticked at Checkers for a trip from Johannesburg to Durban for my son, who was in Mafikeng for an interview, he was going to take the City to City bus to Johannesburg then Greyhound to Durban, he was immediately called and had to stay in Mafikeng, but when i went to Checkers to cancel the Greyhound ticket I was told that if it has been more than an hour after the ticket was purchased they can not help me, I bought the ticked at 11:30 and I went back and stood at the queue which was long, could only be attended at 12.35, the lady told me to call Greyhound directly so they can help me, of which I did but the lady I spoke to rudely said the ticked will be forfeited, my question is WHAT HAPPENS TO THE MONEY THAT WAS PAID, I was not informed about these ridiculous terms and conditions, I feel Greyhound is a bunch of ******* that are *****ing people's money, now I must pay more money for my son to travel, for something that I had already paid for, I feel it's unfair and inconsiderate for this business.
