Telkom FALSE advertising

I had a Telkom DSL internet service installed during May/June 2020, which advertised Uncapped DSL 4 MBps @ R199 per month(COVID-19 discount) . I app**** through DSLTelecom online.

Every month a Debit order @ R649. 00 went off my bank (except for the first month when it was R900+)

After many attempts to access my account through the Telkom App, I managed to receive my account number and link my account online.

Because I only got my account nr in Jan 2021, I could not lodge a dispute.

Eventually I was told that the extra fees were for a HOME phone line rental and another additional DSL line rental, why was this NOT in the ad that they published.??

Do I REALLY HAVE TO PAY R450.00 on only LINE rental and then only when I pay the R199 get the SERVICE that I app**** for @ the advertised price??
