Always get it in writing first period! Always have a DSR (direct sales rep) come to your home and get a copy of the signed paperwork. They will be glad to come out as they only get paid for what they sell. You can also IF doing an equipment upgrade where an installer comes out have them also put it in writing and sign and date the work order that way there is zero confusion as to what is the agreement between you and your service provider.
