Billing error!!

I would like assistance - after 3 years Supersonic has all of the sudden started billing because they found that I have not given their router back - when they have picked it up and provided the new owner with two routers. Kindly advise why use are billing me now and where the amounts came from after 3 years.

I received communication on the portal suggesting that all is well and that my line is canceled. I no longer reside at the address. Please investigate and make sure you do due diligence on your systems and waybill numbers with the courier's use were using then. Fibre companies are making a mockery out of people because their accounts team processes are not up to scratch!
