Ongoing Issue with Telkom Balance and Voice Bundles Purchases

I am really frustrated with Telkom’s service. Last week Saturday, there was no network for about two hours. When the network came back, I was unable to check my balances or purchase voice bundles,and the issue still hasn’t been resolved to date. I downloaded the Telkom app, which shows that I have R105 airtime and R85 free airtime. I even confirmed this through your WhatsApp service. However, despite this, I still can’t use my airtime or buy voice bundles. When I called Telkom customer care, the agent told me they didn’t know what the problem was and advised me to send a blank SMS to 180 but my phone doesn’t allow sending blank messages. I was further told to call again if the issue persists. Honestly, I don’t understand why it’s so difficult to ensure that customers can simply view their balances and purchase minutes. Please resolve this issue urgently.
