Extremely aggrivated angry customer

This is the worst networking service provider EVER. I do not recommend anyone I mean anyone to use this. A WHOLE like manger hung up on me after refusing to help me then she says they will call me back to sort out my issue who h I have been experiencing for 3 months. Same problem every month on the 20th, I have spent over R500 on airtime just to call ****** Rain. I honestly cannot wait for Vuma to come to my area so I can leave this useless thing.
