Paid up letter

On the 30/01/2016 I settled my ABSA personal loan. I then sent a proof of payment to [Email Removed] on the 01/02/2015. Called the call centre on the 02/02/2015 asked to speak to Dylon they said he is not in his desk I then left a massage for him to call back which he never did. I then called them again on the 03/02/2015 they asked me to send an email to [Email Removed] to request a paid up letter which I did on that same day. I have not received any reply from them since then. I sent them an email every day since then. I need this letter urgently as we are in the process of buying a house. Please assist
