Debit my account after payment was already made and refuses to refund me

I am so sick of FNB!

They once again have debit my account with 3 different amounts for my personal loans after I have already made payments on all the accounts as per arranged with Unilaw who are the attorneys who are handling my account.

When requesting a refund of these amounts I get told that they cannot refund these amounts even though they can see the payments made on the 27th because I need Unilaw to send me a letter to say that I infact have an arrangement with them as per my payments.

This is about the 6th time this has happened to me in the course of 2018 and I am now fed up!!

My husband is a private banker at FNB and will now also be moving his accounts to another bank as the customer service is pathetic!

Quick to take your money yet it takes hours of my time and Hundreds of rands on airtime to try and get my money back!
