Just like “Construct Data Verlag” from Austria, another Scam has been started by “Commercial Online Manuals S de RL de CV”, now from Mexico. These people are as much mis-representers as much Construct Data was, if at all they are different from the original crooks.
Their modus operandi is simple. They send you innocuous looking letters on letter heads with bold titles, “Expo guide” or “Fair guide” but their own names mentioned in fine print at the bottom. The name of the fair where you might have recently participated is boldly mentioned and you are asked to update your company details. To prompt you to reply, they deliberately print some of your information incorrectly, like the telephone number or the website address. The impression one gets is that the letter is from the Fair organizers. More often than not most people without reading the fine print would update the information and send the correction in the prepaid envelope.
Once you have sent the correction with your signature, the nightmare starts. These people would start sending you invoices, payment reminders and keep calling and pressurizing to pay for what they have claim to be binding contract.
These are scamsters. Simply ignore them!! Even if you have fallen into their trap unwittingly, simply refuse to communicate with them or be bothered. There is nothing they can legally do, as they don’t have any legal standing. A contract, where one of the parties misrepresents is never binding.
Nevertheless, if you do receive their Business Reply Envelope, do send some garbage into it, so that they end up paying charges for international post and soon become bankrupt.
