It is frustrating when you cannot get ahold of someone at a business and I don’t order anything from those businesses.
At the same time anyone that disagrees with business owners not wanting to waste their time with the time wasters, solicitors, charities, or people that have no intent on buying anything should answer a business phone for a day. You will quickly be able to distinguish the difference between people that need information to make a purchase and people that want information for some other reason.
