Travelstart doesn't value their customers

It was my first time using travel start and I am beyond disappointed with their customer service. When you call the customer care they speak so highly about how they care about their customers, yet I've been emailed and calling for the past 30 mins to enquire about an urgent matter. This is my time and Airtime getting wasted for 30 mins just sitting on hold. When a consultant did answer she told me that it's travel season and they experiencing high call volumes and my Airtime ran out. Is there only one consultant in the whole of Travelstart? She told me that if she puts me through to Mango airlines they will be lenient assist me at no cost to make my changes because the flight was booked a couple of minutes ago and well Mango is another story, the lady that answered was rude as hell. I honestly don't understand why companies employ people that don't like dealing with people and have a ****ty attitude?! Your employers, especially the ones at dealing directly with clients are your main points of contact and affect how your clients see your brand. Extremely furious with the service I got from both Fly Mango and Travelstart today.
