Absa basically giving third parties rights to our salaries we end up with nothing

I did a debit check for one thousand and the third party took 7000. Now I rent less foodless. And this saying you must go after the people who basically stole the money. Like I am loss for words and asking myself where to get the money. But absa must reverse I will transfere to the third party and do away with this debit check because it’s opening up its clients to a lot loss of income our cash is not safe
