Mango going Insolvent?????

I did a booking in June and the website showed an error. I did a new booking but the old booking also went through. I called Mango immediately to rectify and followed steps to try and get my Refund. My credit card was paid up and 2 cycles have gone by with no Refund in sight. I phone 5 times so far, and every agent who answered acknowledged that the refund was due, but claimed Finance hasn't done the Refund. This bull**** story is going on for more than 2 months now. Are Mango in financial difficulties?? For a R2800 refund, it seems like they are stalling as it is free funding for them with my money the last 2 months. Catch a wake up Mango. Leaving a nasty taste in my mouth.
