Absa stupid system spoiled my birthday plans

Absa has just spoiled my birthday plans to spend with my 85 year old mother and father. Yesterday when I was trying to use my money from my business account *** Divene Trading and Projects, to my surprise my account reflects a debit balance of R22 450,27 because of their stupid system which processed the transaction of R25 500.00 I made on the 30th of October 2019, and the money was taken from my account on the 2nd of November. On the 16th November their system processed it again without my knowledge or any notification! I received a payment to my account on the 12th December , sms notification still said I have available funds! Which I don't understand how their system can say I'm in debit balance and on credit at the same time!!! When I visited their branch at Vaal Mall I was told to write a letter - and they send to their dispute department which will have turnaround time of three working days, meaning no food for my parents and I for the long weekend, above all, my birthday today the 15th is spoiled! I want my money released with immediate effect so that I can close my account before something strange happen again which will end me in financial stress or breakdown!
