Unauthorised charge

In April 2024 when I moved to my new place I app**** for connection. Co consultant by the name Chulamanco Mgwangqa assited me. She however failed to check on whether webafrica operates in my area or not even though I gave her the address. Now the router was delivered only to find that t does not work at my apartment. My last email to her was me telling her that she only needed to verify which she failed to do. Nonetheless I went and got another supplier and continued with life. Now tell me why do I wake up today with R999.00 debited from my account. I reversed it. I am not going to pay for an error that was done by you guys. If you want your router please come get it but dnt try and **** me for something thats not even working here in my house.
