Share trading-different views

I had bought some shares at FNB for R300.00 but immediately changed my mind to have the account closed and have them deposit the money back to my account. I was told that I should trade in the shares I did and the first message received was on the 7 Sept 2015 that buy 5 shares RMBT 40@ 43.63 and the second message was received on the 9th stating that an amount of R179.40 was paid to share account. I phoned the very same day and I was told that I will receive this amount the following day after they have taken the brokers fees into account. My share account had always had a R30 balance and I noticed on the 11th that my share account was closed and the R30 was deposited to my cheque account. I made a follow up on the 14th to find out when wil the R179.40 be paid to my account. I was the told that I will only get the R30 because the whole amount of R179.40 was consumed by the brokers fees of R58 per share and I have sold 4 shares before and 1 share later. I am really unhappy as FNB is ripping us and secondly why do I get different opinions.
