Line blocked for R199 missed payment while double debit order went off on 23/09/2022

So my debit order of R199 bounced back on the 6th September 2022.

On 23 September 2022, Telkom decided to double debit my account, as a bonus they then barred my line on top of that.

When I enquired today 26 September 2022, I got told that I must wait for Thursday 29 September for the payment to clear. I asked the consultant, why must I wait when you debited my account?
