SARS USELESS CALL CENTRE

Please will someone explain to me how to get hold of SAS/customs dept. by phone? Today, I called exactly 10 times, each time cut off after 15 mins, then call back again. at 3 when I tried to call back for the 11th time, all services for the day had been closed to deal with existing calls. So how do you get helped if you get cut off after 15 mins????????????????????? No email address to direct enquiries to, so how do we contact them? This service is beyond pathetic, continually going from bad to worse, there is no hope for the government departments in this country, service simply does not exist. It's a crying shame. Not expecting to get a response here either, just venting my frustrations. And then they have the audacity to ask yo if you want to rate their service?????????? WHAT SERVICE????????????????
