Con artists

I bought a flight ticket online and paid R100for my extra bag only to be told when I got to the airport that I need to pay R250 for the other bag, when I asked why, I was told the reason why Lift airline is so cheap is because you pay for all your bag excluding hand luggage. I feel that lift is ******** people, nowhere online does it state that you must pay for all your bags. The stuff at the airport is rude, while I was checking in and asking the lady why must I pay the R250, she decided to leave me there and was busy chatting to her colleague about something else. When I told her that with other airlines you get an allowance for 1 bag, she told me Lift and Flysafair, you need to pay for your own luggage and she just left me there to decide whether am I paying or not. After dealing with that, we were just told by mouth that our barding gate has been changed from C12 to E something, we had to run around like crazy people, only after we were at the boarding gate, an announcement was done. I don't know if your pilots are trainees or what, but the flight was not a very pleasant flight, not at all. I decided to take my complain to twitter, I was told to inbox my details, upon doing that, I was sent an email address to forward my complain there, why did they respond to my twit if they will refer me to other people, why can't that department contact me. I am so angry and disappointed, I am never ever using your airline. Another thing, tis company does not have a contact number, it has only has an email address, which they hardly respond.
