********** behaviour

I had my paid account on the 3rd of October, I did 2 payments. I took a screenshot of my eft transaction and I whatsapped it to my Avon Leader and then to Credit control. I was told that the account I had done the eft to no longer exists. I called my bank and a consultant told me that if that account was closed the money would have been reversed. I always had to pay in order to release my goods and it usually takes between 3-5 working days, after my payment a few days later i received an sms stating that my goods were in transit and should be delivered to me in a few hours. A few weeks later I receive a call from credit control telling me that im in arrears and that I should pay that amount to avoid being blacklisted. I will not pay again as I have already done so. AVON YOU CAN BLACK LIST ME BUT I WILL NOT PAY AGAIN!!!!
