Very Poor service.

I paid my contract on the 28th of June, 2024, and Telkom debited me on the 2nd of July, 2024. The amount for the 28th appears on my Telkom invoice, but the one debited on the second does not. I took a contract that is less than R200 n, but every month, I pay R400+. I phoned and enquired about everything, and they told me that it was fixed, but it was not. Currently, my bill is sitting on R380. I'm sick of this. I log calls on the app, and every time they call me, they either drop the phone or keep quiet and say nothing. I need urgent assistance with this. I must be paid and double debited by you every month; it is a considerable inconvenience.
