Bad service at FNB

I am very disappointed in FNB. They closed my cheque account without any notification. After phoning FNB Customer Service they informed me that my account is closed and there is nothing they can do about it. The consultant helping was helpful and tried to escalate the matter but to no avail. I enquired about my account because SARS made a payment to a closed account. Now I have to wait for FNB to reverse the funds paid to my "closed" account. I stopped using my account because the bank fees were exorbitant! I was and am a very unhappy client.
