Epol horse feeds false advertising

I called into question the fact that Epol were sending out Epol Safe n Lite for horses in a 40kg bag, the tag with the ingredients also stated it was 40kg, to have a fight with my horse handlers that they were over ordering and where was the extra food going. Epol phoned and thanked me for pointing this out and agreed it was false advertising but did not offer any help or say can we send you a bag or something. As I had a huge thing about this with my handlers and falsely accessed them. This is just not good enough from a company that has been around for years and just thinks they can get away with false advertising and a mere sorry will fix it. It is great they will fix it, but this has now caused much tension.
