Bad service +No answers= Disappointment

I am now lost for words FNB. I have been on temp disability leave for 6 months and every month I had to call and email multiple times for you to pay me from my MPP benefit. In July funds (flexi amount) from my home loan account has been taken out and the principle debt amount has not decreased. I had around R22 392 and now it displays R16 000. I have sent 6 emails and no response to assist. I have requested callbacks and not one person called me. Your customer service is pathetic, you supposed to be helping us so live up to your motto of " how can we help you"
