Billing by Trudon that we did not sign for!

Our company is being billed R518 everymonth for a service that we did not sign for. On contacting Telkom, they say its yellow pages entry I have tried in vain to contact Trudon to terminate this billing - Telkom is not helping they keep tranferring me to billing department which is not helping.

Dissapointed by Telkom that they allow their customers to abused in this manner
