Horrid service

In december last year i cancelled my telkom router data via the app. In january telkom debited my account. I called and quoted that initial reference number, they said they have no record of it. So the lady gave me another ref number for cancellation 3***. So she said its cancelled. In february telkom debits my account again. I went to the bank to reverse the debit. They debited again 2 days after reversal, i reversed it again. Im march they debited 2 and half times the amount. I dialled 10210, they couldnt help me, said to call 081180. And to dat nobody picks that number. Telkom is officially the worst service provider.
