FNB POOR SERVICE !!!!!!

Good day, FNB sent a message yesterday stating that they experienced a delay with processing processing vito 30 virtual card transactions between 25th Dec -30th Dec and that these payments will be processed on the 23 Jan. Any fees related to this delay will be reversed back into my account. Thing is I took an FNB Temp loan so any monies reversed back into my account was taken by FNB for toward the temp loan. I received a message this morning stating my cheque account is overdrawn. This is an FNB problem not a me problem. Why am I being charged AGAIN for purchases made in Dec this is a duplicate charge since monies paid at the time was deducted immediately from my account!!!! Please investigate and resolve this issue. Additionally, Mongenzi a banker on the FNB Banking app provides poor service at 4.30am on 23rd Jan think he sleeps on the job as he responded once and not again. Additionally, he is giving me incorrect information.
