ACCOUNT PAID FOR BUT NOT UPDATED ON THE SYSTEM!!

On Thursday 10/12/2015 @ 15:17 I deposited R1300 to my Justine account and sent a proof of payment on Friday 11/12/2015 around 02:30 am. On Saturday morning @ 08:33 I phoned credit control and the lady that I spoke to said I used a wrong reference number which is incorrect. today is the 14th nothing has happened my account is still showing that I am owing. I'm reporting this because it is not the first time this same problem occurs, even last month I couldn't place my order because of this delay, I'm even thinking of deactivating this account and stop selling Justine! I have an account with Avon as well, Avon is so accurate, I've never experienced any problems with them.
