6 weeks to activate cell number on security gate

Impact Alarms installed a new gate access system at the complex I rent in. The new system was installed so that residents would be able to call the gate open by cell on top of the existing ability to open by remote. It has now been six weeks since the system has been installed and despite almost daily requests by email for the last four weeks I still can't call the gate open. We were provided with a single new remote to open the gate but must pay for a second. I don't see why if we should be able to just phone, which was the point of the upgrade. It is becoming a real inconvenience as my wife and I both work and must share a remote. I'm very tired of the empty promises.
