Unhappy Loyal Customer

To whom this may concern. I've been with FNB for so long and never encountered any problems or at least that I took note of, but recently especially in the last 2 weeks I've been heavily inconvenienced with regards to debit orders and money being taken out of my account which shouldn't have been taken out. On 30th March 2016 I took out a loan for 6 months but paid it up or settled it on the 28th of April in full. I could've left it as is and just pay the normal instalments for the remainder of the months but because I wanted to be out of debt I paid it up in full in less than a month. I then had a direct debit come out of my account the next day for the instalment of the loan which shouldn't have come out which has now inconvenienced me in so many ways and have spent 2 days in which I had to stay out of work and loose 2 days money which I would like to have paid back and compensated for from FNB. I have a son to support and today again I was at the Tokai branch and was told the money will be in by today which I was told Friday as well but to my surprise I was taken for a ride again. My son can't go to creche now because that was his creche fees and my elderly mother cannot look after him so can you how this is affecting my life right now? I seriously don't think that I have to go through all of this to get my own money back. Just like you have a job, I have one as well and I don't want to loose it by staying out every time to chase my own money and still not get it. I would like to have my money by tomorrow morning in my account as well as compensation for all the fuss I had to go through and money I had to spend to go to the bank twice and loose 2 days money at work, and if that cannot be done then please provide me with the contact details if where I can escalate this and take this matter further.
