Procedure is call the City of Joburg call centre 0860 56 28 74, report the missing bin and get a reference number. Usually easier to get through after hours, they operate 24/7. Go to Brixton SAPS and do an affidavit, stating your case & including your reference number. Email brixtoncommunity@gmail.com with your reference number and street address. Keep the affidavit for when the bins are delivered, Pikitup will need it then.
