Bad customer service! ************* bus service!

If a zero rating was possible that's what it would be. The worst customer service and interaction EVER! I purchased a Intercity bus ticket on Computicket for a family member and got a purchase confirmation email. However, when she got to the bus they refused to let her in because apparently we had not paid for this ticket. The drivers were rude and would not allow us any time to resolve the situation despite the fact that we asked for time to do so by calling your offices. I contacted both Intercity and Computicket Travel and their agents were all rude and very unhelpful. The person waiting for the bus was asked by the bus drivers to present my bank statement to prove that payment was made, and even though I found this very uncomfortable and invasive of my privacy, to ensure that she was safe and in the bus I sent her the bank statement to give to the drivers. I found it very unprofessional of your staff considering that you have a partnership with Computicket to sell tickets to your customers online, and when there is an apparent system error all your customer service agents are unhelpful and rude towards those very same customers, and would opt rather to leave an elderly woman on the streets. This has to be the most appalling customer service I have ever experienced. From both Intercity (especially) and Computicket!
