Card machine payments not clearing

I am extremely livid that I have once again have to wait for my money from my card machine to clear into my account! EVERY month on more than a few occassions, especially with weekend transactions, I have to call into the call centre after waiting 4 days for my funds to clear. (No proaction on their part in the first place.) Then only to be told i have to wait another 48hrs for the funds to clear!!! And now this has happened on MONTH END - When my debit orders are due. Then all I get from call centre and Manager Thandeka is - Sorry for that Sir, I will call our sales department to look into the matter... What Bull**** type of service is this! When I asked why this happens all the time, they claim that they are verifying the payments.. WHAT!~!!!! How am i supposed to run my business when I have to check up on my card machine clearing everytime? What happens when I miss a payment due that hasnt cleared? Why am I paying thousands of rands each month for this inconvenience and Disservice?! I am now stuck with no funds in my account, and pending debit orders (ONE OF WHICH IS THE CARD MACHINE FOR THOUSANDS!!!!!) and all response I can get is "sorry" from a Manager, adding Another hurdle for a small business to overcome!!! Can someone please look into this as I am sure I am not the only one experiencing this. Call Centre lady I called @ 08h31 today is Shandise and she escalated to Manager Thandeka. My ref # is ***5
