i was refuse to go in with my laptop and textbook

I went to discount store at gundi square main street time 10:10 18/02/18 to buy some stuff the guard told me I must leave laptop and my expensive textbook on the parcel counter and I insist went in ask the manager he told me if it is not groceries I don't have to leave my things by the parcel counter. I bought my stuff and as I went out by the exit side the are pupil who tick the receipts they told me I need to exit by entrance site where the fat guard who refuse me to go in was sitting I went there and he started swearing and pushing me inform of his superior nothing was done by the manager of the store. there customer service is poor you will think I was there to buy on credit even management does not intervene when they see the is a problem by the door part of management just went out and drove off. we don't need such service in south Africa even wonder if the store is registered and if there guard do go to training for customer service. I'm furious with the bad service i got from the discount store.
