Telkom Billed me for Devices i don't own.

When I app**** for my router the system had problems, therefore devices where not appearing on the system. Only to find out that they are actually getting captured under my name. I was therefore billed for 3 devices for my first installment I am being informed I am going to be billed for cancellation fees, when I call to find out when will my money be reversed. I need my money to be returned and I am not going to pay any cancellation fees as that is not my problem if their system is behaving abnormal. Been calling and going to the branch since 16th October still my issue is not resolved.
