I want my money from Mr Riba at Ermelo Transnet.

I was asked by the post manager for a bribe of 2500 in order for me to get a job. Out of desperation I paid R2000 to Mr Riba at Transnet He gave me an application form if which I filled yesterday and said he will get back to me. From this morning Mr Riba has been giving me the run around and now he is no longer answering my phone call.
