$59 was the cost of the upgrade to the new digital system. My monthly fee went up but I figured it was worth it. System didn't work all that well. Telsco kept sending their very excellent technician to troubleshoot- to no avail. Not only did Telsco not charge me the upgrade fee for as long as it took to fix, they replaced the entire system- no cost to me. The office response was amazing and their technician was his usual amazing self when he came to install the new system. Telsco Security has a customer for life. They were and remain absolutely superb. Highly recommended.
