Missing airtime

I recently experienced an issue with Vodacom of missing airtime on my account. On the 7th of August 2025 to be specific, I was charged R19 for subscription services, of which on my end I don't have any subscription services and I haven't had them for years. On the very day, at 18:40 I was charged R18.65 for call that didn't even last 3 minutes. What happened R1.65 per minute? It's even more frustrating trying to establish communication with Vodacom customer care because all you get is TOBI !!!!
