I was on a trip from Biarritz to France, booked 1D place near window for almost 5 euro. As a result, driver moved me from this place into the second row in the center. Couldn't sleep. Customer service is not responding and I have to wait long time to contact them by phone. Still haven't get any email or phone call from them.
Will switch to deuschebahn in germany and ouibus in France even though it's more expensive but stable.
Hope they'll be replaced by some more reliable company
