Terrible correspondence

Hi Sars - I have done absolutely everything that was requested to complete my return. The last correspondence was on 1 August to verify my banking details - I submitted everything immediately. I only now get updates every week to say my refund is wittheld due to my banking details being verified - 25 business days has gone by since I submitted - also every week you say you strive to complete this process in 10 working days - once again 23 WORKING days has gone by. Can someone please assist me in getting my return paid out?????????
