BAD SERVICE - CONTACT CENTRE

I have been trying to contact SARS for days. Each time i call, i wait in the queue for close to 2 hours. The consultant answers then tells me to hold on so she can check my profile, and cuts me off thereafter... after holding on for 2 hours! The same thing happened today, i reached the front on the queue and was cut off again! How are we supposed to liaise with SARS if this is the service we receive?
