Overseas deposits

I have started working for an overseas company who pays my salary into my account. I sent them instructions as per the Capitec website, as I had 3 hours notice to depart South Africa to go work. On returning to South Africa I discovered that my salary which had been paid on 18/03/2015 did not reflect and was referred to the Call Centre who in turn referred me to Foreign Exchange. foreign Exchange is either understaffed or do not bother to answer their phones for me to get this sorted out. I have my daughter's wedding to attend this Saturday and it would appear that I will miss it now. Really disappointed!!!
