Well,I told them (police)about the incident at the supermarket,he smiled shook his head and took a description of the bloke,shrugged his shoulders,filed the case and told me that they are understaffed.
On the way out he quitely told me, if I catch him make sure it looks like an accident when I do a violent citizens arrest.
And I thought South Africa was bad...
Report it to the Police and detail all the issues you have had (missing out the bit about clouting the bloke). At the same time, do some homework regarding who's got it in for you and plan your revenge (don't detail it on here though for purposes of legality).
