Trapped at Jusco Autogate

I was trapped at JUSCO Kinta City Autogate for more than 1/2 hour due to 'Black out' in Ipoh Garden area. The autogate won't work and there is no backup power supply which is enough to sustain the system. I was disappointed that Kinta City management had failed to contain the problem in less than 1/2 hour. They should have anticipated that power failure in Malaysia is quite common due to power cable theft, poor maintenance and other kind of nonsense reasons. I believe the losses on this night is quite high as the cashier system, most of the customer just dump thier trolley and walked out frustrated. This means extra work for the workers to place back al the items and clean up the area. Theft is also possible since the RFID scanning device failed to function.
So the point is "Please get a better BACKUP system".
