Telkom no clue what they doing

Hi. So I got a contract from telkom at the end of June 2025. My phone and watch was delivered first week in July. My payment was due on the 1st of August 2025, but when I checked my app it showed do on the 31st of August. Telkom send me a email that I am due the first installment because the debit order was declined. Although there was money in the account and I had no notifications from my bank of any rejected debits. I was reluctant to do a EFT because of previous bad experiences with telkom mobile.when they were 8ta. I was double and triple debited in the past. So on the third I paid the first installment via EFT. On the 6th of July I got the email stating that I am in arrears with the first installment and due the second installment the end of the month, not reflecting any payments that have made and also stating that I would be charged interest for a rear accounts. I responded via the app stating I would like a call from a agent. They phone be back about 30 minutes later but some reason I didn't hear the phone and I missed the call. No call back after that for 2 days. I responded again on the 7th and the eight and the 9th it requesting a call back from the agent. No reply not responds via the app or sms or email. It's the 11th now and still no respond but at the end of the month they want to charge the interest and debit me double. Telkom clearly has no clue what they're doing. The admin is non existent and no customer service. This is a new contract but it leaves a bad tasty burnout and I still got two years ago . If you want bad service go to telkom otherwise stay away.
