double debit again??

As a freelancer, I do not earn a set income. Avon and Justine are a side hustle for me and I really do not make much from them either. I am now finding it a nightmare to deal with the company. Especially when it comes to paying your account. Today I paid my Avon Account and was debited twice, this is now the THIRD TIME this has happened with Avon/Justine. And my reason for jumping on here for the second time is that the last time this happened with paying my Justing account, the website was faulty and I landed up paying three times. Not to mention, the attempt to pay the week before which was processed (via the app) I was charged a penalty of R 50 for late payment too. Then when I requested they refund the amounts I paid in error, it took them over 30 days to refund me. Emails were sent, calls were made, I got no where and then finally restored to social media. Only then was I noticed. Still, denying receiving my emails even though I was also told to email them to direct email addresses. I then contacted Wendy Knowler on Twitter and only then did they wake up. However, from date of error to the refund is unacceptable, ESPECIALLY WHEN THE MONEY IS NOT YOURS. I was told to send all supporting documents, bank statements, proof of payment etc which I did in every email. They dragged their feet and then still deducted the R 50 penalty. To add insult to injury, one of my debit orders was returned, costing me R 105 in banking fees, had Justine refunded me in time, I would have had to incur that cost. To make matters worse, their customer service and their attitude to this debacle is disgusting. As a person who lives from month to month, sometimes earning nothing, to KEEP MONEY THAT DOES NOT BELONG TO YOU IS UNACCEPTABLE. It is ********* and immoral. This time, I will expect my refund in 7 days. The money has left my account, I understand it can take up 48 hours for moneys to clear. Worst case R 72 hours. I WILL NOT STAND FOR THEIR SHODDY CUSTOMER SERVICE AND ********* BEHAVIOUR AGAIN. They will receive an email from me and I will give them until Tuesday close of business to respond! To add to this complaint, I have brought this issue to them with their website over and over, as there is clearly a glitch in the system. I only approved one payment to AVON today, yet two transactions went off?? HOW IS THIS STILL HAPPENING? The website logs you out as you make your payment. Then you try log back in and there is an error, you try again and then finally you log in. If your account is over due, you land up with a message on your page as you log in with the overdue amount, even though you have paid it! This happened with Justine back in March and also with Avon several months back. That incident I never got my money back was credited in my account. ONLY I DONT PAY MY BILL FROM AN AVON OR JUSTINE ACCOUNT. If my refund is not actioned in the 7 working days, I will pay a visit to head office the kick up a fuss. A big fuss. Avon Justine need to up their game. Their delivery process and products are awesome, I have never had an issue with delivery of my products, however their customer service and LISTENING TO THEIR REPRESENTATIVES leaves allot to be desired. I am demanding my refund this time, with in 7 days.
