TERRIBLE EXPERIENCE -No Records of Returns on my account

I sent returns in July 2017 with a Manager Natalee Kruger, she made me sign a slip written "Returns without picking slip" I signed and she signed but till today the return is not logged on to my account now I have an overdue for the return which I gave to her, now it seems like she resigned in September 2017 and I was sent details of the new manager Max Tsonope , and I have been escalating my matter through to all the emails at Avon and there is no resolutions, they keep asking me for waybil which I do not have, and now this is affecting my credit record and i very bad now no one seems to be able to assist and when ever I call there is no answer from no body namely Chantel Nel, Max Tsonope, Natalee Kruger nothing at all, Avon is just a big whole to ruin our credit records, never in my life will I be selling Avon anymore, people BEWARE, Now im getting sms about ITC Blacklisting my name due to this.
