Proof of payment send but not reflecting

On the 10 March I placed an order and received the billing on the afternoon 11 March payment made 12 March before 10 am at the branch but until this day, the payment is still not reflecting. My account is a prepaid, Monday I emailed my leader proof of payment and an email send immediately to Avon but until now nothing is reflecting & and; going on leave so how would the people get their orders. This is being happening since December 2015 but my colleagues get their orders in time or maybe just maybe...
