Payments not reflecting URGENT

I have been an Avon and Justine Rep for over 15 years. I pay my accounts weekly. I have made two payments one of 04 April 2016 and again on 8 April 2016 Neither payments are reflecting against my account. They now have to do an accounting journal which takes an additional 10 days. Well we are past the 10 days. When I place another order by the end of the week my order will automatically go on hold. We are in the 21st Century How is it things take so long. Payments should reflect within 48 Hours The error was not on my side. Nothing has changed my end, Please sort this out ASAP. Please sort out your slack service in credit control...Shocking
