Horrible experience, automations that don't make sense

I'm having such a horrible experience with Vodacom. I called customer care and was directed to a robot. Robot is not asking which number I'm calling about. It just says it seems I'm not using Vodacom number and tells me about stupid SIM porting. I used whatsapp n whatsapp wants me to use the same number that's blocked. Does that really make sense? The number is blocked why am I expected to use it when communicating with Vodacom. ×135# also want the number that's blocked to request puk number. All these things doesn't make sense. I can't even work now since yesterday coz I can't confirm OTP on my work system my number is blocked
