Currency Rate

I ordered Forex through FNB on 24/02/2015. I received a call from Twala indicating that my money was ordered and that I should go through to Bidvest Bank to collect on 26/02/2015. I'm quite disappointed though because I did not get a good rate. The rate I received was 2.58 to the Thai Baht. When I went onto Bidvest & FNB online I saw a significantly higher rate when I went in to collect my money yesterday. I queried this with Twala yesterday but have received no feedback. As from when do they do the rating? Is it from the time I ordered the money or from the time I changed it, which was yesterday. I was not advised by Twala of these details as this is my first time exchanging currency with FNB. Surely you should be looking after the clients best interests and should be giving them the best rate possible. This is the second time now since becoming a platinum account that I am receiving this bad service. Please help!<br> <br>
