But don't you take on a contract based upon a survey, based upon detection being present, and it complying to the type of service your providing and you then give them a contract based upon this , walk test it service it and means you are saying that it works according to the contract you have given them
How can you then say sorry we don't guarantee anything because previous company programmed it , and we are just giving you contract based on nothing ?
I must be missing something?
