Missing EFT Payment

I made an immediate payment to my fnb easy zero account over 48 hours from my absa account for the amount of R19 699 however it has not reflected in my fnb easy zero and i logged a ticket number with eft queries/missing payments and the team leader for eft missing payments Cecile Lupke asked for my case number to investigate and she has not responded after numerous follow ups I have done to find out if this has been investigated and where my money could be. I just called absa now and they confirm that the transaction was paid successfully to fnb however it's not reflecting in my fnb account and it was an immediate payment but absa is failing to assist its tracing the funds and reversing them back to my account as this is heavily impacting on me financially. Can I get customer service or some sort of assistance please.
