Not happy

I’m really disappointed and angry for the experience Wesbank put me through for the past 2 days, on the 10th of august I did transfer to my account for my monthly instalments not sure why it was not taken on the first, on the 11th my account was debited with 2 months installments which is 13980*2 which left my account on the negative. 1. Now I have a negative credit with my bank they might not trust me for future finances because I’m owing them because of Wesbank that took my money and didn’t bother to assist me when I called telling them I’m stranded because that money was meant for other plans I sent the proof of payment but guess what none of them bothered to respond or apologies I spoke to Mathlatse mkhonto who advised that I call again on Saturday which I did and I inform him that last Saturday their lines were off and he said they opened till 12 when I called because I really need my money the voice note said they are currently closed I’m really devastated because it’s a weekend and I need that money for something very important here now broke and no where to go Up until now still no feedback from them I’m not taken seriously and I don’t know for how long do I have to wait from them.
