Mango customer service what a joke

the first and very last time I will TRY to book with Mango, since yesterday I have been trying to make an online booking for Sunday from O.R Tambo to Capetown only reason I was willing to give them a try was because they price was very good , yesterday I made my booking selected my seat and ready to make my payment but it does not want go to the payment page I cancelled and tried again, then my seat was taken so I phoned and asked for help to receive my reference number still no luck getting into the payment page ok fair enough I decided to try again today maybe the Mango website was just offline and by my surprise they cancelled my booking so same story I selected my seat and ready to pay the web site still stuck so now Ive given up and phone to ask for help I speak to a very abrupt bombastic lady by the name of Ingret asking what I want to do and the more I try to explain I just want to pay my booking I understand that the booking from yesterday was cancelled but surely the one from this morning cant be cancelled so convinced me to re-rook and wow to my surprise the price went up R300??????? what?? within an hour so now I must pay a higher price because the website doesn't allow you to make payments? Is this some kind of scheme to pretend that they are cheap but keep on cancelling the booking until a few days before and then you must pay the higher price? When I told Ingret I will then rather book with SAFAIR because they are cheaper then in that cause she answered me sarcastically so seems like MANGO makes enough money they dont have to care about customer care or helping new customers by the looks of it
