WhatsApp customer service line a joke

After being a customer for years, we had to cancel our month to month menbership as we moved into a new property that had an existing active fribre account at no extra cost. We attempted to Cancel our services on the last day of December 2023 for end Jan 2024. Webafrica acknowledged the request with no further feedback - we followed up daily and only on the 4th of January did they get back to us stating that due to there being public holidays that we breached our 30 days and will be charged for FEB and only then will the service be cancelled. We have proof of communication from both us and responses from webafrica from the 30th December 2023 until 4th January 2024 being passed from department to department avoiding the cancellation. The have subsequently still tried to debit my account and will be trying to do so every 24 hours incurring more costs to me.
