WORST SERVICE EVER!!!

I have had endless problems for the past few weeks. Worst of all is that the owner always seems to be on a business trip when one has a complaint. I struggled and fought for a week for them to get my son registered as he is a student and we use them often. I finally received the discount code which was supposed to have been received after 24 hours a week later. One can only make an online booking and get the student discount so I went ahead keeping the email with the code open to make sure I follow the steps. Entered the code and paid and thought, okay that was easy. So I then decided to book the ticket for his travel back to Uni as well. When I got to the page to confirm I realized that the code was never app**** even though I added it and paid full price. I immediately called and reported this. I was then promised that I would get a callback and that the amount can be adjusted and I will get the difference paid back. Needless to say that never happened. I had to call and speak to Rachel who then said no the manager said they can't pay me the difference and they never said that. Mind you I checked and even on the email, they said they would re-in\mburse me. A bunch of unintelligent idiots who don't have a clue about customer service. It seems that you only get service once you badmouth them. DO NOT EVER USE THEM. The drivers are awesome though!!
