Capitec lack of empathy and sympathy

I made an arrangement with capitec in December as I was and still is unemployed. I had a casual at checker for the first couple of weeks in December. They deducted R800 as agreed up and no mention of i or anyone should not leave or transfer money into my account . My brother transferred R4000 into my account to keep money aside for groceries as ramadan was coming up and to my surprise they deducted R1 368.00 twice . I could not reverse it on the app called call centre 7 times and out of that 5 dropped the call after explaining the situation calmly and without me finishing said nothing will be reversed as my loan is in arrears the date for the 30th moved to “as soon as their is money in my account they will deduct what they need to . Not taking into consideration I’m still unemployed but in the process of awaiting for work calls . I went to branch as I was advise only the collections dep can reverse it and the branch can reverse it . After I explained everything and the consultant calling the relevant team and they won’t reverse it cuz my account is arrears . The branch manager said that they should as per collections duty is to advise you must not pay anything into your account. If I made an arrangement, stated and provided all the documents needed for unemployment and date provided if i should somehow manage to get money where it’s actually says salary they can deduct this was money saved by my brother who is the sole provider of me and my freaken pregnant sister who lost their father during the pandemic and grandparents in the same year sent to me to keep for coming Ramadan to just take twice and take it as another and not people trying make it with one salary level 2 . If they mentioned to me when we made the arrangement that I should not receive any money that’s not mine in my account that this could have avoided but they didn’t and now my family has go to hungry because of their failed system and service provided .
