SARS - TOTALLY USELESS STAFF ON THE PHONE - CAN'T ANSWER A SIMPLE QUESTION

The staff have absolutely no clue how to answer a problem over the phone. I have now had to phone 6 times I have had 6 different stories and still no one can sort oput my problem. They have linked my cell phone number to someone who has not paid their tax for 8 years and I have now received 977 text messages demanding my tax returns. My tax returns have been submitted on time every year for over 40 years. PLEASE CAN SOMEONE SORT OUT THIS PROBLEM.
