ONE WEIRD TRICK - dirtbag companies HATE this - my mom (former lawyer) taught me to get any company dragging its heels or otherwise being scummy about giving you what you paid for is to basically state what you want followed by “...and if I do not get the product/service that I paid your company for, my next call will be to the State Attorneys General of the state of (where we’re from) and the state where you are incorporated, and we will be filing a claim of fraudulent business practices.”
9 times out of 10 that’ll be enough to get the gears moving. Legal compliance is almost always more expensive than fighting a customer on an issue, so they tend to give in rather quickly.
