Postnet - Bad Service!

I went to Ballito Junction to have sensitive and personal documents shredded only to be told I must leave them all with them and when they had time they would be shredded --- this is utterly ridiculous = why would I want to shred them if they werent very personal and private!!!!! This is ridiculous!!! I then went to Salt Rock branch only to be told they dont do shredding! What bad service! Wont be using Postnet for anything again!
