ET Nice Centurion technical advice

On 20th August I phoned them for technical advice after the gate showed "battery " alarm.This is after I replaced the battery. They promised to phone me back but never did. In desperation I had to get a gate installer to reset the system , which was a 30 seconds job ( 2 wires pulled out and put back again) and cost me a call out fee of R657. Maybe they don't give technical advice on the phone to force consumers to call gate installers .Poor service!!
