Delay in payment of refund

After phoning SARS this morning. You wait 30 to 45 minutes to get through. The lady was not interested in helping. I wanted to escalate the audit. My tax return has been in since the beginning of August ,support documentation requested and filed ,then after 60 + days more support documentation requested . Ridiculous stalling tactics to delay payment on tax returns especially since the details could of been requested in the initial support documentation and 80% of request was not applicable just stalling. Disgusting !!!!
