Shockingly Poor Service from Travelstart- I was left stranded

I booked an Airlink flight from Polokwane to Johannesburg leaving at 7:55 am via Travelstart for the 17th of Dec 2021 and a connecting flight via Airlink from Johannesburg to Cape Town for the 17th as well leaving at 10:35 am. To my horror, i received an email from Travelstart informing me that my flight from Polokwane had been moved to 18:00 on the 17th of Dec 2021. No options as to how we can re-arrange my flights, no response to the watsapp messages, no answer when i called the land line. How does an agent simply make a decision on my behalf for me to fly at 18:00 instead of 7:55 am as booked? They are so poor at customer service that they dont even mention how this affects my connecting flight nor did i receive any help in trying to rearrange my flights. No feedback in this regard. I pleaded in my communication for options as i was travelling with my toddler yet i received no assistance from Travelstart. When i approached the Airlink concierge desk to try and find out what had happened, i was informed that they had checked with Travelstart regarding moving the flight from 7:55am to 18:00 and Travelstart had agreed to the change on my behalf without consulting me. NEVERMIND THE CONNECTING FLIGHT I HAD BOOKED VIA TRAVELSTART TO CAPE TOWN. As it stands, i feel ****med out of my money for the cape town flight which i missed because Travelstart agreed to a change in flight times without consulting me. The fact that they can see on their system that by changing my first flight, they will be ensuring that i missed my connecting flight didnt matter to them. No refund, no communication. Poor customer service. Indeed if you value your peace of mind, stay away from Travelstart. When you book your flights, your account will be debited immediately but after that, you are on your own even when you confront challenges which arise due to them making decisions on your behalf and not bothering to communicate nor even assist you with re-arranging your flights.
