SARS has the worse service

Dear SARS.i submitted my tax return in July but since then I have been chasing you for my refund. You asked me to provide documents for banking details verification and I did but I still her sms informing that this verification is in process and will take 21 working days. We have way passed 21 working days and your call centre stuff have run our of excuses. I raised a complaint with your complaints department and they didn't even bother respond tp my query. If I was the one owing you,you would be chasing me,charging me interest and penalties but now that the tables are turned around,you don't care.
