disgusting service

I am extremely annoyed by the service Greyhound is proving to their customers , I have made bookings for my family first week of December from Harrismith to Durban on the 31st December online , everything were okay until yesterday morning when I received a call from these people informing me that there will be no buses for me on that day therefore I need to change my bookings !!! HOW??? what about my accommodation and other commitments? I asked for refund , that lady asked me to call me back, 4hours later I phone their irritating call center and their put me on hold for more than an hour . Then I decided to go Bosman bus station to their offices as if that was not enough drama, that lady said I need to wait for their call center manager to authorize the refund unfortunately they cant give me a refund as call center manager is not available. next day I called call center again , now Lean is giving me a total different information and she cant assist me with anything but escalate my query and wait for them to call me until Jesus comes back. now I have to cancel my books ,nxa!
