Half the complaint calls that came in were from customers with units so broken the vendors were at a loss, but the other half were from customers just wondering about proper usage, and so alternate tollfree numbers were set up and operators were underpaid in India, every Indian who had never been accepted to engineering school following the troubleshooting/FAQ script—Does the unit have batteries? Does your unit have separate or joint On/Off buttons? If separate, are you pressing the correct one? Or both simultaneously? If joint, are you sure the device is not already Off? Or On? Are you operating the remote within 28 feet or 8.5 meters of the equipment you wish to control? Are you pointing the remote correctly, in the direction of the equipment you wish to control? The lines busy, the holds long, clients calling from their carphones in traffic, put on hold for longer than traffic, only to be disconnected, getting picked up on only to yell about how previous calls had been dropped.
