We contacted GDS because our garage door opener stopped working, thus not being able to automatically open and close our garage door. The GDS technician advised us the garage door opener was no longer working and needed to be replaced. This he determined simply through what he heard. When my husband suggested to the technician that he open the garage door opener, he said he did not need to do that because he could tell, due to his professional experience, by the sounds the opener was making. Additionally, he advised us that there was no tension on the door, which essentially burned out the motor in the garage door opener. He advised us the torsion springs needed to be replaced as well. The technician then gave us an estimate to replace the garage door opener, torsion springs, set of new rollers and labor in the amount of $787.05. He said this estimate was the best price he could give us, and that it would only be good for 4 days following his visit. The was his hard sell. After weeks of not using our garage, my husband decided he would make an attempt to fix the garage door himself (after a few You-Tube videos later). Upon opening the garage door motor cover, my husband discovered the problem to be a simple disconnected wire. He re-connected the wire and everything worked as normal and has now for a week. We were completing taken back when we found the solution to be as simple as a disonnected wire. This reads like a Dateline Investigation story I have seen all too many times....customer is naive and company attempts to take advantage by selling what is not needed. Also, we should have been charged the $29.95 service fee (we had a coupon) to simply reconnect the wire, however because he did not service the unit we were charged a $49.95 service call. This company not only acted fraudulently, they pulled a bait and switch on us. Wow...it is amazing that companies exist like this!
