My payment. Never processed thou paid

I have been a representative of Avon since 2019 ...I made an online payment on the 10th of November 2021 through online payment and the money left my account and received a notification from my bank that it's gone to avonjustine account but it did not reflect on their side

R390 I paid when I noticed it didn't reflect on their side I contacted them and I was told to contact credit control which I did and they kept asking for proof of payment to which I sent my bank statement and screen shot of the text it was the only roof I had .

More than 3 time I sent the proof and I am still requested for what should I do now? I heard about Hellopeter from a friend and I decided to give my review,,,I ended up not paying the other amount though I have it. But what if it does the same? credit control is it helping. A d Avon said there is. Nothing they can do
