Inconsiderate Company

Vodacom has truly proven to be an inconsiderate business. My mom's phone has been giving us "line busy" when we call her the whole day, but she is able to make calls. I decided to call customer service on her behalf. Firstly there is no option to choose for this problem, then I chose any option so I may speak with the consultant. Which ever option I chose all were self help, non to speak with the consultant. My problem is not registered on your self help voice notes, so how do I proceed. I can maybe chat, but I truly don't have time for such. It got me thinking how you have evolved to discard others from a country that still bleeds from the illiterate and literate. Had it been my illiterate mother 77 years old with over 17 years of using Vodacom network, she is immediately eliminated. Highly disappointed.
