To be fair, Facebook messaging and a company's advertised, direct email are very different things. I actually agree that if a company can't field a general query via email then that company needs to have a good hard look at itself as it's likely losing sales. It shouldn't be up to a customer to modify their preferred way of contacting/obtaining info to purchase a product, especially with big, detailed decision-making like building a performance engine. The last thing I want when I'm not 100% sure of something, is to be talked into something prematurely, or paying more than I have to. An email can also be sat on, mulled over, compared and used as back-up for quotes etc. Plus, it is 2020 after all...
