GreyhoundRSA ****med us off our money!!! Utterly Disgusting!!

We booked a dreamliner for R1 300 however GreyhoundRSA decided to bring us a citiliner without informing us beforehand, furthermore we were told that we won't be refunded. What is the point of having our phone numbers if we aren't informed of this inconvenience. The worst and disgusting fact about this whole ordeal is that, GreyhoundRSA refuses to refund us for the balance. We paid for a comfortable and spacious bus but did not receive what we paid for, we paid a lot of money to not be refunded. We made numerous calls only to be placed on hold, our complaint via email is being ignored as well. WHAT THE HELL GREYHOUNDRSA!! YOU FAILED TO DELIVER! DON'T IGNORE OUR REQUEST FOR A REFUND. Customers shouldn't chase you for their hard earned money when the fault is on your side. I am going back to Intercape, at least they understand professionalism and put their clients first. Is this how GreyhoundRSA makes money off people?
