Monies held hostage, no service, neighbors covered

I was informed my area is covered and the sooner I pay the sooner installation will be done... I have been following up and today I was informed that they do not cover my area which was not originally said. If I was not persistent then my monies would have been held hostage even though SLA has expired, nobody could tell me that I am not covered. After purchasing data for my smart box and airtime to follow-up and knowing that my neighbor uses their services, unbelievable. I feel like they have miscommunication in the company and make interest off our monies first...
