SARS NOT PAYING MY REFUND THAT IS DUE

My refund was recalled by SARS on the 18th of July, WHY. I called Standard Bank and was told my account is all in order and that there was no attempt to pay money into my account. Everyday I call SARS to try to resolve this issue and am told they cant tell me what is wrong or they tell me it my bank or they also told me its being reviewed while I have not being selected for a refund. This is unacceptable and I insist that SARS respond urgently with a constructive resolution and time frame. I was also told by a SARS representative that this has happened to many Standard Bank clients
