Causing Trauma to the elderly and keeping promised refunds

I booked a flight for my elderly father and his carer to fly up to JHB so that I could move him into a frail care close to me. At check in, Mango told the carer that he could fly but my dad could not as he was too old. I then had to pay for car hire and the carer had to drive my father up to JHB, which caused him huge stress as he is wheelchair bound. This happened on the 7th of January and to date (25th February) I have not received a refund for the two airtickets,despite being told by Andile at Mango Refunds and an extremely rude "supervisor" called Chantal on a seperate occasion that it would be paid. My father suffered complications from he car journey as he was not supposed to be in a confined position for 7 hours and has since been hospitalised and died.

Is this how Mango treats it customers? I am sickened and disgusted at your behaviour. You dont refund what you promise either - Empty promises and ****er service - in the worst possible way!
