I just moved my office and it was time to upgrade my phone system. My local dealer installed the TDA50 system, which seems much better than my old system although the dealer has been a nightmare to deal with. When they installed it they said they would hook up the music on hold when they came back to do the training. It took them 6 weeks to give us training on the system and they said they couldn't hook up the music on hold until I ran a cable from our stereo receiver to the TDA50. I ran the cable and now they won't return my phone calls. Can anyone please help me? I would really appreciate it. Thanks.
