Ingenico Problem

I'm a business woman with a Standard Bank Ingenico Merchant Devices.. I have been experiencing shortfall in my account every week when the money is deposited into my account. it does not add up to what the summaries on the machine reflect. This has caused a big loss in my business as the business is making money but what is credited into my account is way lesser to what the business has initially incurred. I took loans but still there is a shortfall I even fired my employees because I couldn't pay them.. now my business is about to close I AM SOO FED UP... when i call the call center they are sending me from pillar to post... I went to the Standard Bank branch and the consultant sent an email to the company and they still haven't rep**** I DON'T KNOW WHAT TO DO I'M FRUSTRATED i cant even pay my bills anymore...
