Disgraceful customer service!

I booked a ticket for an employee on Mango's website on 04/09/2017. There was an error when the SID payment was processed, which resulted in the amount being deducted off our account, but the payment wasn't allocated to the booking. Accordingly I did not receive a booking confirmation for the flight booked. I initially contacted SID payments, who in turn lodged the payment allocation request with Mango. I also contacted Mango directly (after holding for 10 minutes!) and sent a lady called Sipho the proof of payment. She said she would forward it to the correct department for manual allocation and would come back to me by close of business. This morning (05/09/2017) I follow-up with Mango Airlines as I had not received the promised confirmation. In total it took me over 15 minutes and 3 internal transfers (!!!) in their call centre to finally get hold of a supervisor by the name of Shadnam, who promptly told me that there is nothing she can do but escalate the matter to her "IT Department". I then also followed-up with SID Payments who received a confirmation from a lady called Nadia Pretorius (Senior QA and Support Analyst) that the matter was being addressed - this was over 2 hours ago! We have been out-of-pocket without a booking confirmation for over 24 hours now. I don't understand why it takes so long to sort out such a relatively simple matter?! All-in-all, very disappointing customer service!!! I will definitely think twice before booking Mango Airlines again in future!
