FUNDS DISSAPEARANCE

I am rather disappointed in the manner which my enquiry is being dealt with, on the 16/12/2021 I tried transferring funds from my capitec account to my fnb account using an immediate payment option of which was at a cost to me, funds were never received but left my account Capitec account. I tried to request a statement from FNB PLATINUM PARK(POLOKWANE),the statement showed funds were transferred tothe Fnb account,out of frustration as to what happend to the funds I asked the bank to investigate and a very rude lady in the name of a MANAGER told me there's nothing she can do,really? A whole high profile bank telling a client there's nothing she can do,this left a rather bitter taste in my mouth as to this is the kind of a service one ought to receive,up until today m waiting for the funds,still nothing
