Morrisons review: Security

I was in Morrison's at Canvey Island yesterday when I was approaching by a security guard who asked why I wasn't wearing a mask. I told them I can't wear one at which point he called over the other security and said I swore at him and laughed. They all then surrounded me and tried to force me out of the shop. When I refused one said he will punch my face in and called me a pussy. This continued all the way out of the shop. I have video evidence of this and will contact my solicitor for advice.
