Credits & ITC

I received a sms yesterday with an ITC against my name from Avon. I don't owe Avon any outstanding monies. But when I logged onto my account, there is a popup that says OVERDUE. I can't understand why, because I send my order back to be credited on 10/11/2014. After almost 5 months I would have thought that someone at Avon would have done their job in crediting my order.<br> In Jan'15, I had to cancel an order due to the credits not being done - so I phoned and contacted my Avon leader and she assured my that it will be done, but I have to remember that Decembers don't count, as no one works over Decembers.<br> When I spoke to Susan Koekemoer, her response was \send the return document through and I will look at it". Then I phone Avon and get a reply \""we cannot help you"
