What the hell is going on in sales call centre

I have been trying to register for an landline for the past 2 days. I go onto the Sales Online Chat service. Agents do not respond or cut me off by deactivating our chat session. Then I requested on numerous occasion to be called back. My phone rings immediately but agents either do not speak to me, speak to each other or hang up on me. If this is the type of service you render when attempting to obtain a new customer i dont even want to know what type of service existing clients receive when having a query.<br> Can someone please contact me in this regard. An agent who is interested in obtaining a new sale or even better a supervisor. <br>
