Slow very bad service

We have changed our banking details last year and SARS had the correct banking details , this year we now have to confirm banking details because the banking details on the IRP5 was wrong AGAIN, my husband sat in the line at SARS Randburg today for 4hours with NO HELP at all, you know we are actually working people there is NO way that we can sit at SARS offices day in day out until we someday get some assistance YOU want us to confirm details and we have to do everything to keep you guys happy and informed of everything but what on earth are you doing to make things better for US the guys that actually are the reason you have jobs...No Sars your SERVICES are REALLY REALLY BAD you should be ashamed of yourselves..
