Vodacom Cancelations is Pathetic

My father in law had a home internet contract with Vodacom. The contract was supposed to end November 2024. On 1/10/24 @ 18h03 we phoned Vodacom and canceled the line. They said the last day of the contract would be on 30 November. We spoke to Andile for 26 minutes. Ref *** They debited on 1 Nov again on 1 December. 2 January 2025 they debited more then agreed and from February 2025 we canceled the debit order. Now they have handed my father in law over. He send an email on 5 Feb and still haven't received feedback. Ref: 002***SU97UCMSN. He mailed them again on 20 Feb also no feedback. ***
