This is happening too often to be a fluke. It's typical for a prospect to talk to the same few competitors in my field. One, in particular, has been lying about my product straight up on multiple occasions. I've seen the fwd'ed emails from the competitor's sales team. They are aggressive and telling nefarious lies about my product (wrong pricing, incorrect info about our API, etc.).
Prospects are following up to double check but this is getting out of hand and very annoying. This has been flagged by management and they've reached out to said company about the misrepresentation but it falls on deaf ears. (No surprise there...)
I don't like bashing competitors (I don't even mention the lawsuits that people have filed against this company). What other alternatives are there to combat people who give sales a sleazy name...
(I'm currently working on getting testimonials and letting the prospects talk with clients to assure them that those things aren't true).
