Incorrect billing & ignoring you.

Supersonic Invoiced me for a router in 2024. I paid & received it. August 2025 they add that same charge to my account. I have logged numerous complaints & all they do is respond on things other than my double charge query. I have sent proof of invoices, payments of the invoices & their statement where the payments reflect yet they ignore me & now owe me over R1000 for something they double charged. Every time I log a ticket, they reply with something else dismissing my question regarding the double router charges. I sent a thorough detailed email full of proof and even highlighted everything for them & they ignore that part. Now what? They need to be reported because I need my account rectified.
