Our verbal requests (completion date and thin grout lines), we're not included on an invoice that we signed and paid the deposit from. We never received the expected contract, but rather an emailed copy of the same unsigned invoice. We were told it WAS the contract. When the job was finished, the 3 day job took 10 days to complete, and the job was not done to our requested specs. Do our verbal requests and the fact that it was an unsigned invoice give us any leverage in small claims court?
