Please help me Peter

I was approved for a temp loan at FNB on the 16/11/2020 and when it paid out same day, I transfered the funds to my savings account. This morning 17/11/2020 I wanted to use the money so I transfered it back to my cheque account to draw it out. To my surprise and frustration, FNB kept deducting all the money I transfered from my savings. Went to the bank stood in the line for an hour and they told me that they cannot assist me because their phone lines were down. I am sleeping furious and wish I had never done this is the first place. This is so wrong on many levels. Even branch managers at FNB Zewenwacht Mall could not help. Stupid people almost gave me a heart attach. I was late for work as well to top this **** off. Wakhile Lebetloane ***
