I signed a contract between my company and another company in KS. It's been 6 months since then and we didn't receive any signed copy of the contract (original, mailed or faxed). Is this contract valid? Another thing is that the contract doesn't contain any specific details about payment, amounts or date and time of delivery. The information is very vague like "once a quarter" and nothing more.I didn't say they didn't sign. I just said that they didn't send us any signed contract. Ok, once a quarter is a enforceable action date but... the "quarter" is not defined in any way. It's like we are working with them for 5 months and we never received any money or statement from them. We just have no idea what is happening there.
