Waiting almost a month for my refund!!!

I accidently made a double payment to AVON on the 17th December 2015 to the amount of R1305 I sent an email the 19th December 2015 and to date have not received my money.I was sent an email on the 28th advising that my refund is being processed and will take 5 working days to reflect in my account to date still no money!!!! I am extremely dissapointed as I am fairly new at selling on AVON and right now feel like I want to cancel my account with them...really pathetic service from the credit control department!!!!!
