I had a problem with the locker of my apartment as it was not functioning correctly. I called Antwerp security and they made an appointment for in 2 days. Someone cam over, looked at the locker, tried different things, and at first he thought the locker might needed to be changed, but he suggested to try something else, and in 5 minutes the locker was working perfectly.
It was appreciated his honesty, he could have just installed a full new locker and charge for it, and he decided to try an alternative. In 20 minutes the locker was working perfectly.
To me, and given the importance of a locker, the price was very correct, service was fast and honest. If I need it, I will call again.
