Technical Error ........ Or something like that!!!

My frustration lies with the fact that my brand new My world account with my Salary paid into it is now useless as Everytime I want to do an online transaction the same stupid error message come up stating " we have detected a sim swop, please call 08*****. I call the number and the consultant tells me that they are having a technical issue and it will be fixed by Sunday. Please bare in mind that I am out of South Africa and penniless so I have no choice but to wait it out. Sunday comes and goes and I still cannot transact. I am beyond livid. This is ridiculous!!! How can they justify leaving people without their own money because of a IT issue and when they tell you there's nothing they can do about it, they have this ****y attitude almost making you feel bad, like you have bothered them with your silly problem and you should just wait and keep quiet while doing so. ITS MY MONEY and African BANK IS WITH HOLDING IT FROM ME AND I NEED MONEY TO EAT ETC!!! MAKE A PLAN, HIRE MORE IT GUYS, FIX YOUR TECHNICAL PROBLEM WITHIN A FEW HOURS NOT DAYS BUT I CANNOT ACTUALLY BELIEVE THIS CAN BE ACCEPTABLE PRACTICE FROM A MAJOR BANK?????? I just want my own money with the approval message sent to the registered number of the account. No changes have been made whatsoever since the account was opened. I'm not in the country or I would physically come in and talk to you people. Please sort this out as a matter of urgency!!!!!
