Pathetic Service at the Customer Care Centre

Visited centre on 30 December 2017 intending to purchase a charger for a Samsung S7 Edge mobile phone. A number of customers waiting at reception desk but no one present to assist. After waiting for some time a security official put up a notice at door indicating that the centre would be closed on 30 December and would again be open at a date in January. I decided to leave but the security official told me that because I was already there I will get assistance. So I waited and at that point the security person closed the security gates that you could not exit. I asked one of the staff who was walking past whether they stock chargers for the phone. Answer was negative. So I asked that the security louvre be opened so that I could leave. No security person in sight and had to waste my time further until it was opened after some time. Very unpleasant experience. No option other then to visit a nearby cell phone shop and purchase a generic charger.
