Payment not reflecting on Statement

Good day<br> I have received a statement for June 2015 which reflects that I have an outstanding balance for May 2015. I have made payment, a direct EFT as usual from the same bank account using the same reference on the same day as every other month prior.<br> I even emailed the proof of payments to the accounts department.<br> <br> I have yet to receive a response as to whether my account has been rectified.<br> This is very unprofessional and *********. I am definately rethinking whether I should actually renew my contract when it expires end of the year.<br> <br> Please fix this urgently or lose another customer.<br> <br> My account number is A*** -***<br> <br> thank you
