FNB deplorable customer treatment

I've been sent from pillar to post for almost 2 months now and all I want to do is get FNB to remove a hold on my account. They asked me for documentation and I sent the documents a month ago, and all I keep being told is that my query has been escalated and that it should be resolved in 3 days...it's been 2 months now! Utterly unacceptable and deplorable treatment I have received from FNB
