Experienced and helpful consultants
They have very experienced, supportive and helpful consultants. They try to sell the product that we really need. Not more than that. They have a lot of experience on safety. So they can direct to the right solution and devices. We've been using the solution for about 1 week and we're very happy with that.
Good experience while installation
Fast and flexible customer service while installation
trustworthy and long stadnign company
The company has a long standing history and has trustworthy and competent employees, very good quality price offers for your safety!
Great service
In the beginning the service was a bit unsatisfactory, but now that the new system is up and running, everything seems to be in order, and the service is great.
Excellent Work
Lionel was excellent at explaining our options, helped us make the right choice and made a perfect installation.
He subsequently invited me to call at any time if I needed more assistance
Very satisfactory solution, but big room for process improvment…
G4S provide very satisfactory security solution, their customer service is very good. however the main challenge is to get things going in the right track and the very lengthy response time. so I think it's such a big company with many departments that the internal coordination and process are in need of review and enhancement. The customer satisfaction is negatively impacted by their internal process not by the actual service and solution they provide.
Excellent service
Value for money spent.Works as it…

THE WORST SERVICE COMPANY I'VE ENCOUNTERED
THIS HAS TO BE THE WORST SERVICE COMPANY I HAVE ENCOUNTERED. They are impossible to reach by phone, huge waiting lines!! When their call back facility finally activates after 10 mins on the waiting line, they do NOT call back!!! They do not answer my mails. I want their crap removed from my walls to use another security system and I cannot get hold of them. DO NOT CONTRACT WITH G4S. You can do far better. It's cheap, perhaps, but it is not worth it. in NO way. They are utter crap. Over rationalized. Horrible service.
