Immediate Transfer

I transferred R20 000 from my Capitec Account to my Fnb Account with immediate transfer on Thur the 19th Dec. The money left my Capitec Acc and never reached the Fnb Acc, I did another transfer of R300 as a test and it went through and reached the Fnb Acc too. I called Capitec bank on Friday and spoke to Thando and was given this Ref no. ***9, I was told they need to investigate and will let me know but there was no feedback communicated to me on Friday. Sat I went to a Branch in Stoneridge and the Manager there called the call centre to follow up and he was given another Ref no. ***3, there was no feedback too on Sat. This morning I called the call centre again and was given Ref no.***2, this matter is still at the same status it was at last week no feedback as to where my money is hanging or when I will get my money back.
