NO customer service

This has by far been the WORSE customer service i have ever in my entire life experienced! I bought a ticket online @Mango on the 13th of Aug 2017. I get to the airport with my 2month old baby 15 Aug 2017. They tell me 3 different excuses as to the money i paid directly to them does not reflect yet and i must pay for another ticket now but the will refund my the money for the previouse ticket asap. This is after i have showed them ally proofs of payments emails cobfirming flight ect. So now i buy another ticket and the same day i get on the phone with them email them, NO RESPONSE FOR A WEEK. PHONE THEM EVERY DAY SINCE 15AUG 2017. USED R200 airtime and they never get back to me. 10days later they tell me they will do the refund (after i phone & email them again!) So last week monday i compain again and follow up again as to where is my money, tuesday last week somebody on a no number phones me from mango telling me my money will be in my account no LATER THAN THURSDAY LASTS WEEK. TODAY IS THE 12SEP 2017 AND STILL NOTHING????!!!!!!! I CONTACT THEM EVERY DAY ON FB, AND EVERY TIME THEY TELL ME THE MATTER HAS BEEN ESCULATED. SO IF ITS BEEN ESCULATED EVERY DAY WHY IS NOBODY CONTACTING ME OF ASISTING ME?????? WHY AM I PHONING AND EMAILING EVERYDAY AND THE ONLY RESPONSE I GET IS WE HAVE ESCULATED THE MATTER. I have on several occasions ask for the mangagers number there, not once anybody replys on that email. And the 2 times they phoned me after i posted on social media they phone me on no- numbers. WHAT is going on there?????? Do you have staff working at Mango???? You take my money so quick, but ive been waiting a month for my refund that was A MISTAKE ON MANGO'S SIDE. NOT MINE!!!!
