money transferred via internet banking is missing.

a collegue sent an amount of R300 to my account using standard bank Internet service. this took place on the 27th of March. both my colleague and I are Standard bank customers. as of today we both have spoken to 4 different consultants and they have all been giving different explanation and none of them are able to track where the money is. could we please get some assistance as the account number where the money was transferred to was correct. today is the 9th of April and yet the money has not reached the account. so it looks like the money has gone missing and no one wants to take responsibility or assist in resolving this matter. this incident has left me in doubt about Internet banking.<br>
