account in arrears

<p>Hi, I have an account with Avon which is in arrears now, on the 27 December 2016 I made a payment of R150.21 to my account in which was done using cellphone banking(transfer)....I sent an email the same day to ********** to check if they received the money or if I made mistake with the referrence number in which I have not received a responce I checked on my online avon account to check if my total owing has reduced in which it was still the same....only to get a message from avon saying that legal action is to be taken regarding my account.i have the proof that shows that I paid that amount..what I dont understand is why my account doesnt reduce after payment and why I cant get a response through the email I sent to them</p>
