We are not taken seriously

I'm sitting with internet while I pay a premium, I have called customer service agents, they escalated my incident they promise that someone will be in touch but nothing. To day I called the the agent made me hold for ages until I ran out of airtime she didn't even bother to call me back. Its been three days I am sitting without internet connection. I have to buy data what's the point of all this. I am very disappointed Rain this is not Good
