I completed a contract and requested payment. The General Contractor then told me that they had typo's in their contract caused by their secretary. The contract had left out items they say they wanted me to supply. I supplied all items in the contract. The contractor said that since we had discussed the full amount of items needed prior to the contract, I am bound by their intent of what they meant to say and not what the contracts wording actually states. I say if it's not in the contract, i'm not doing it or providing the item.
Am I wrong.
