Closing my account after such humiliation

Just when I was making my way in the store my shoes beeped, security took my bag let me pass to verify if it was really my shoes that went on. I explained to him they normally do that. He told me I can't get into the store, because he would have to strip search me or I would have to take off my shoes to make my way into the store. I had to argue with him to enter the store until I called a sales assistant , he couldn't help me either ,he called the manager , when she came she also suggested I take off my shoes. By that time other customers were looking at me as if I was convicted with theft. I'm a regular customer in that store and an account holder I never thought that I would one day beg to spend my money in a retail store that I'm loyal to. I logged a complain immediately after leaving the store on the website they haven't responded , even called the store asking for customer complaints number it took me to voice mail , I left a voice note but there's still no answer 4 days later .I'm really disappointed by the service of Foscini group its Extremely Bad
