Very angry passengers

I hate kulula I bought flight tickets yesterday and chose a date but when my tickets came the date was wrong now they say I must pay for changes which are more than the ticket amount I've been calling kulula no one is helping to send da link so I can pay the service is poor the consultants are chatting and laughing sies

I WILL NEVER FLY WITH THEM NEVER EVER AND I WILL POST IT ON EVERY NETWORK TO TELL NOT TO
