Telkom not responsive

I have been trying to cancel my business landline since APRIL/MAY. I phoned various times, I emailed, I completed forms, I wrote cancellation letters on my company's letterhead attached my ID, my line has been off since May and I paid up to June. I have been to Telkom at Ballito Junction 5 times now and no one is helping me .. I even received Aug statement now again.. it is ridiculous
