FNB pathetic service again

FNB contacted my wife and I in January with an offer to upgrade my premiere account to a Private fusion account. The agreement was to have the account for three months at no cost to us, to see the accounts benefits before we upgrade. After the first month the started billing me the monthly private account fees although our agreement with Portia that there will be no charge. A private account consultant called insisting I sign the new acc agreement although we agreed that it will be on a probationary period. I informed the Portia to revert my account back to the premiere account on the 1st 9f March 2022. I had an overdraft facility on my Premiere account, 0n the 4 of March the private fusion account restructured my overdraft facility and took all my available money from my account without any consultation. This is the pathetic service one must become accustomed to when dealing with FNB. God only knows how I will feed my family for the rest of the month. FNB wants me to take another personal loan with exorbitant interest rate to feed my family. This is how FNB cares for its customers.
