Ask an employment attorney what it would cost to send a cease and desist letter, documenting this misrepresentation and potential fraud. This starts a paper trail in the event you need to file suit and seek damages. They may cover the cost if their internal legal team is unable or unwilling to send such a document on your behalf.
What do they even hope to accomplish with that? Get you hired? Or bait & switch the client? In any case, you should talk to your company's legal team (and not randos on the internet). Whatever the former employer is doing, it sounds like it could have the effect of sabotaging your new company's business or reputation with that client, which could be illegal.
