Made a complaint in Feb 24, now June 24 and no response. Staff on twitter lied when I highlighted this and exclaimed " we respond to all complaints ". Why would you lie like that? Then more recently I was scammed by the creepy straw-haired Asian woman at the streatham branch. B*tch got more front that Southend. She charged me for a whole pack of envelopes when I only bought 1. Stole my money by refusing to rectify her mistake. Told me there was no one I could complain to. Say what? Wonder how much she makes on the side scamming people. I now refuse to be served by her, let others go ahead of me so I can end up at a different desk because I can't afford to be robbed again. Spoken to others in the queue and evidently she is well known for stealing from customers. Nasty woman with bizarre hair. Looks like she tortures it daily.
