Capitec is *****ing money!!!

Just got the rudest awakening with Capitec Bank! Trying to make an online purchase and it kept failing, my limits were set high enough. Then I had 5 CHARGES of R3 something of credit limit exceeded without any warning or notification???!!! Then I call the call centre only for them to tell me that there is a R50k international limit dealing with an incredibly obnoxious and rude individual stating this to me!! If this matter isn't resolved and my money refunded for policies you DO NOT MAKE AWARE TO YOUR CLIENTS I WILL CLOSE EVERY ACCOUNT I HAVE WITH YOU!
