No Communication and Non Existant Customer Service

My last message from them was "Let's see if we can get this installed for you on Monday. We will be in contact". Today is Monday, and when I queried this, they told me that they sent a cancellation request to SADV.

No communication from them. I will never recommend them to anyone. Instead of providing proper service to customers, it's literally like the customer has to beg them to give them money.
