Disappointing call center service

Took a mobile contract July 2020. Telkom failed to place debit order instruction with my bank. The would often get cut every 2nd month and reconnected after their collection department has debited my account. On a number of occasions I've called and emailed without getting assistance. I only discovered that the company never placed an instruction to process the debit order on the 9th August 2021. My credit profile is a mess. None of the agents ever logged a case until the until today. I am very disappointed with their service.
