Highly disappointed and frustrated

Bought the GSpeak Ultra which came highly recommended through various security specialists. Since it was installed we had numerous issues which leads to a huge security risk. First there was lots of interference on the calls coming from the gate station, and then no sound at all. After numerous attempts to try and resolve this, the security specialist returned the unit to Centurion Systems and they confirmed a faulty microphone. A new unit was supp**** to our security specialist who then once again installed it. But alas, our problems quadrupled: Calls are barely audible, calls are not being diverted to the secondary number even though the call limits were set to 10 seconds, and to top that off, 100+ tokens went missing overnight?!?!. Centurion, you need to explain/assist in getting this resolved. We cannot afford to pay a security specialist labor costs for 3+ weeks to get a system installed without any assistance from you on why this system is not working the way it is supposed to/marketed as. Awaiting your urgent feedback
