Bad service received from Mango Airlines

when I was booking the Natwo tickets , I have selected the payment option as "Internet banking - SID". but the process did not completed so I did the EFT and gave a call to Mango Call center. the Call center agent gave her email address so I have forwarded the Proof of payment on Oct 24, 2018, 6:39 PM.

Agent confirmed that she received the proof of payment and told me that she send it to IT department to resolve. I spoke to call center agents to find the status of the confirmation on 25 Oct 2018 and 27 Oct 2018 , not happy with their attitude.

Very bad experience with the Mango call center agents. today (27 Oct 2018) I spoke to Two agents they both put me through a line which I have to wait for more than 5 mins and after that the call gets ended. what a waste of time and airtime to call Mango call center.

Here is my booking reference number. I will never book a flight with them in future. I have booked this tickets to travel on Tuesday (30 OCT 2018) ,still I am waiting for confirmation. what a bad service.
