Receive a letter stating bank charges will be sort

I don't know if this reached the correct social media as well as the branch manager not attending to his responsibility regarding customer care......<br> I have complained about the back charges being so high at FNB on my trust account and received a letter from fnb stating they will correct my charges going back to July 2015, letter was received on 31/12/2015 and my bank charges remain the same with no credit passed as per their letter stating this correction will be made from July 2015.<br> So much for customer service...... This is so sad to let a branch like meyerton get a bad name due to a commitment letter from the branch manager carry no value..... I truly hope they pull up their socks as this is actually an embarrassment..... Being with FNB for years and this is the kind of service you receive as a long standing customer.....
