Disappointing service from Mango

I did an online booking—reference number was provided ....for 2 passengers with the following names: Mrs ......P – date of birth was supp****- passenger 1 Miss .....P - date of birth was supp****- passenger 2 To my under disgust and surprise when I tried to do an online check-in I noticed that 2 tickets were in the name of passenger 1. I was then left with a situation where I had to pay an additional R270 to effect ‘ A NAME CHANGE’--- I THINK THIS WAS UNNECESSARY AND UNACCEPTABLE. I spoke to Marcia at your guest care service and her response was that my computer did an autocorrect and that a refund would not be possible. Only an insane person will book 2 tickets for the same flights on their name. The second issue is that both Mango flights on the specific day was delayed by more that 45 min. I had to attend a funeral in Durban and missed that too—I think their service is utterly disappointing.
