Not happy .....no proper feedback , Terrible service , I will not support this business!

I made a payment to Avon on the 19th October 2018 , but by mistake put in my ID number rather than account number. I immediately sent the POP to Avon and let them know and asked them to update my account. I have been emailing everyday since then and to date this still hasn't been done , my account still shows unpaid. I have sent more than 10 emails now. All that happens is I receive emails from credit control that someone will trace it , what is to be traced I sent the picture of the deposit and I gave my account number , it was a direct deposit. Is nobody in finance actually working at Avon , yet you expect us to bring in more clients and get more clients to buy from such an establishment?
