Shocking admin service

ABSA Stockbrokers support is really gone to shocking. Over 24 hours wrt a simple question on my portfolio, assigned a case number but I can almost guarantee you no-one will get back to you. And whenever you phone, always always always "we are currently experiencing high call volumes" and a 25 to 45 minute wait. My son e-mailed them to ask why he is being charged a monthly fee on his new trading account, when I don't get charged - he e-mailed a month ago. The charge has gone off again. NO REPLY WHATSOEVER. Can anyone suggest online trading platforms with low fees? I think I'm moving.
