Irregular billing practices

I have been attempting to contact Telkom for over a month, but despite sending a message on Twitter and engaging in a chat, I have received no response. Specifically, I requested the support email address or the complaints department's contact information.

In June 2024, I was notified that I had been overbilled for May and June, with a promise of a refund. However, I never received the refund.

This month, I received an invoice stating that I owe double my contract amount. This apparent error suggests that Telkom is engaging in irregular billing practices on customer accounts.

I urgently require:

1. A valid email address for submitting complaints. 2. A thorough review of my account to rectify the discrepancies.
