Telkom Cancelation

Telkom account ********** 43328 I have been trying for 3 months to cancel my Telkom business account. All the requirements were met and sent to the relevant email address. Twice I called in to follow up. Both times the operator promised they would come back to me. At no prevail! The last operator advised me to direct a complaint in social media! I am dumb struck! I am paying for a service i no linger have or want. What appeal do i have?
