Unable to speak to a Consultant as SARS

I have been unable to get through to the SARS contact Centre since last week. I am on hold for 2 hours and then just as i get to the front of the que, the call drops. We are a Professional Accounting Practice, and we are now unable to get answers for our Clients from SARS as it's impossible to get through at all! Is anyone else experiencing the same? Please may you confirm if there is an alternative form of communication, as we need answers for our Clients!

PLEASE SARS!!!!! HELP!!!!
