Payment not reflecting

I have recently joined AVON as a representative, I made my first payment full amount for my account on 27/02/2019. It is now 12/03/2019 my account shows it is over due. I called the AVON call centre on 07/03, they told me that the payment is not reflecting, I must send them proof of payment. I sent proof of payment on 07/03, the next day I recieved an email saying there was no attachment on my email. I forwarded the same email as the attachment was there, same response no attachment. I called again on 08/03, the call centre agent asked me to send the email directly to her as she will forward it herself to credit. I called again today 12/03, I get told there is no attachment. I explain that I sent an email to an agent last week, the guy says he will forward the email to credit so that they can do a journal which will take 14 days. That is unacceptable as the agent I spoke to last week said the same. How is this going to affect my credit record? 14 days is too long just for journal to be processed. I'm starting to lose interest now in AVON. Please rectify my account, I do not want this to affect my credit record negatively.
