We had an issue with our glass break in our home. We called ADT and they sent out a representative to review our alarm system. The lady who came out informed my husband and me that we had to upgrade to new equipment to be able to be compatible for the 3g to 4g switch. She let us know that our current system could not be used and we would need $1600 worth of new upgraded equipment to keep our system. The ADT representatives came out to change out our "old" equipment to the new equipment. They asked my husband why we were changing out our equipment that all we needed was to change a chip in our current box to upgrade to 4g. They wondered why we were changing everything out when our current system was compatible. Julee Vansant In this current state we are in where, we are having to watch what we spend with not being able to work and earn income. To quote that we need $1600 worth of new equipment (which we were going to have to spread over payments) to only needing an upgrade is ridiculous. We appreciate the workers who came today to let us know we only needed an upgrade and not $1600 worth of equipment. Please have the representatives who come out to evaluate the system to either know what they are talking about or not to push expensive equipment on customers Once again she said we had to have the $1600 worth of new equipment to switch from 3g to 4g when all we had to have was a chip replaced.
