Question
I requested a specific job from an engineering office, and they added something on their own that I did not ask for, and I even confirmed with them three times before completing the work not to make this addition. Am I obligated to pay for this increase?
Answer
I say, and with God's help: If there is no agreement on the increase, they do not deserve the payment for it; because it is one of the benefits, and benefits cannot be established without a contract, which is the agreement, and God knows best.
