False accusation *****ing at Spar

So i just left "Spar the Stadium" In North End in PE. Having a security want to search me after I paid for my goods. When requesting to know what suspicious activity I just did, no response is given and when i requested for a manager i was told they on lunch and the instruction came over the radio. Who gave the instruction? Got no reply. Was dressed in a suit coming to buy food and supplies while on lunch from work. Now every person walikng out of spar isn't being searched but I must stand there with two securities blocking my way out. When the manager eventually came... their reply was i was mistaken for 2 other men who were behind me wearing a backpack, yet those same guys walked out without being searched and if they were searched. I still wasnt being told its a mistake or being let out to go. Now every other patron that I normally see there is left with an impression of i walked in to ***** a R20 item yet im carrying a full plastic bag. No request for my proof of payment. Just an i need to be searched. A verbal apology was only given after i wanted to return my goods and get my money back and also attempting to call my colleagues in the car outside to return any goods they paid for. Now the security claims it was a mistake and they were saying on the radio the other guys must be searched. I found the initail handling of the matter distasteful. And the answer that the manager or supervisor is on lunch also disrespectful and an way of saying they won't get them yet they claim they just said they spoke to them on the radio. I will continue to lodge complaints on every platform I find as I just got back to the office and this is now a joke that i left saying im going to go by food... but instead I'm going to ***** at spar. Or the fact that my family had to hear the initial accusation of i must be searched while i was calling them on the phone to check up on them. The humiliation and anger this has set in me is not something im taking lightly.
