Fnb *****

I have had issues with First National Bank and the Covid relief fund in May 2020 and this seems to be re surfacing. After checking my account charges over a period of 3 months I noticed that the supposed installments for the Covid relief fund were very different to the agreed amount. The agreed amount of which was sent to me after I requested a detailed statement which was not available otherwise! Not only is the installment amounts now different but much to my horror they are being deducted as much as four times a month! No wonder I am poor!!! I have tried on numerous occasions to email and make telephonic contact with someone to assist me after I received 14 text messages saying that there has been adjustments to my card, adjustments which I had not authorised. What is going on here?? Is this ***** as I have had this problem in my account before!! I need clarity here Fnb. The sooner the better.
