SIU spokesperson Kaizer Kganyango told TimesLIVE on Thursday that they had requested documentation from the department regarding the tenders. “We have already started. We have sent a letter, as per our legislation, for request for documentation yesterday. Today [Thursday] we have followed it up with a physical letter where we sent somebody to go through [to deliver it]. We don't want a situation where people say they didn't receive it.”
