Billed for products that i did not receive

I have been billed by Justine for products that I did not receive. I have sent emails to their credit control department and I have been sent form pillar to post because they want an invoice/proof of payment and I keep telling them I do not have proof of payment because I did not receive the products and I no longer want them. its been over a year now and still nothing is happening as a result this is affecting my credit report.

Can someone please assist in this regard because I have received and sent emails to these people and nothing was solved: Pearl Williams Khosi Ndlovu Mosibudi Kola
