TELKOM SPEND LIMIT INCREASE WITHOUT PROPER AUTHORISATION

I've been a Telkom contract holder for years. My spend limit was increased without my authorisation 2 years ago. I requested Telkom to set the spend limit to RAND ZERO PERMANENTLY due to the fact that my nephew was using the particular sim. I never had any problems with the spend limit since then, until I discovered this month that R10,000 had been spent on my account. I contacted the accounts department and they started investigating my charge that the spend limit had been increased without my approval and in contravention of my previous agreement with TELKOM. Case ***0. I received a notification via SMS yesterday notifying me that the case had been closed. No feedback was provided. I phone the accounts department again this morning, who informed me that the case was closed because I am liable for the amount due. I believe that TELKOM acted in contravention of the Consumer Protection Act for not obtaining my personal approval for the increase in spend limit and resultant enormous bill. I have demanded a formal response from TELKOM which they are refusing to provide me. I will be submitting a complaint to the Ombudsman if this matter is not sorted out before 30 November 2024.
