Capitec, Nicole and Avukile in the call Centre are useless. Rude, not helpful and poor system

I got paid on the 23rd Jul 2021. That same day I purchased online ( R756 )at Woolworths. Woolworths confirmed my order, payment successful and they sent me an invoice. On the 26th I purchased for the amount of R1570.15. I even received an sms from them of the purchase and a deduction from my account with the new available balance. On the 26th I moved all my money from my savings account and transferred to my flexible account and left few change. Today, the 28th Jul, I transferred R600 into my savings to buy groceries, and my card declined with a 0 balance. It turns out the Woolworths online purchase, R756 and the Clicks purchase R1570.15 were hanging from the 23rd until today. How pathetic!!!! I purchased a R40 airtime to call the call centre. I spoke to Nicole, I told her that I am using airtime, may she please call me back if the call cuts, she agreed. She put me on hold for 30 minutes. I dropped the call and she never returned my call. I called again, and I spoke to Avukile. He was able to see what the problem was (the story explained above), but he was rude. I am frustrated by what he is telling me, but he expects me to remain calm. He was irritated and put me on mute for more than 5 minutes. I dropped the call, I didn't get assistance from this two Consultants. Instead I am left with 0 in my account, I cannot transfer any money, because if I do it will be taken away, I don't know why. I am left with a negative balance of -102. This bank is useless. The other banks are better than this stupid bank with a poor system.
