I think Flixbus is actually a scam and they actually don't run the majority of the buses they sell seats on. The ticket counter staff at Heathrow told me they cancel coaches everyday forcing customers ... I think Flixbus is actually a scam and they actually don't run the majority of the buses they sell seats on. The ticket counter staff at Heathrow told me they cancel coaches everyday forcing customers to buy last minute tickets on other carriers if by lick there are available seats? Also I have still not received my refund. Avoid at all costs and regulators need look into to shutting them down.
