FNB extremely poor service

FNB has been virtually impossible to reach during this lockdown period, and when you do reach someone, they can't assist and refers you to another eternally unavailable person. We have tried our best to make arrangements with FNB, but they do not get back to us, yet on the other hand keep sending us threatening messages about our home loan. I think it is extremely poor the way that they treat loyal customers during this difficult time!!
