ABYSMAL SERVICE BY FNB

I have experienced the most debilitating experience with FNB , there was a Covid19 relief prompt on my APP & i clicked on it to check what it entailed but logged out/aborted the mission as soon as it requested supporting docs , a few days later i saw some movement on my bank account where there was an additional account added onto my profile BUT for some pecu**** reason the funds were credit onto my cheque account, assuming this was a Covid19 relief loan & considering there were no terms & conditions explained after failing to get hold of my banker for clarity I used some of the funds but lo & behold, FNB then rectified their mistake & put my account in a staggering minus &this affected the next funds being credited into my account, i then can FNB for the two weeks on end trying to find out as to what transpired and i was sent from pillar to post with no solution nor getting my expectations managed, FNB has put me through a very difficult time , i have not paid any of my bills for this month so far due to the funds being taken without my consent , i have been following up to no avail, today is the 10th of June & i'm still awaiting a resolution to the query. i was met with sheer arrogance & the disturbing paralysis from their time in resolving this matter has left be in a very compromising position. My lights are about to be disconnected and my rental remains unpaid to this day & I still have not bought any groceries for my children.
