I also feel that this is happening more and more, since there's more rewards for giving very small pieces of attention and energy to a bigger pool of people, instead giving extra energy or attention to a smaller pool of people seeking for one's help.
I'm just facing this with a contractor doing repairs in my house, a month ago was finding a decent mechanic to fix just 2 issues on my car.
The first promptly finds energy to discuss things it receives through social networks or messages, but can't provide a decent list of things that I need to provide him to finish his work faster.
The second case took a lot of time and discussing with 6 different mechanics, until th car broke and it was towed.
I'm seeing this more and more, unfortunately.
