Terrible Customer Service

I am 73 years old. I purchased a scale in January 2015 which disintegrated in my hands on 18 June, still within its 1 year guarantee. I returned it and the Supervisor, Vanessa, refused to accept it. She loudly and repeatedly accused me of dropping it, which I kept denying. She also refused to contact the manager when I asked. In frustration, I threw a very small piece of the scale down onto the counter, a piece of which bounced across and hit her finger. Vanessa was obnoxiously rude throughout the ordeal tried to provoke me to hit her, accusing me of throwing the glass at her, and threatening to send me to jail. I asked another staff member to call the manager who sent Vanessa away and gave me my refund. While the manager was helping me, Vanessa returned, holding her finger up, showing a tiny bead of blood on the end of it and started pacing back and forth with a belligerent pout, trying to intimidate me. Vanessa has subsequently laid a formal charge of assault against me and I am to appear in court on Monday 29 June 2015. This is frivolous and a waste of legal resources, and shines a VERY bad light on Clicks as a company!
