Service Cancellation - still being billed 3 months later

Cancelled Telkom service & fiber line 15 June and still receiving a bill for it. I have phone 3 times to sort this out. Still not sorted. Held on for 45 mins today in a queuing system to where I was eventually cut off. So frustrated I wish I could actually give them a minus star rating. PLLLLLZZZZZZ call me to sort this out Telkom!!!!!

Worst service ever.
