Why do many people dislike intermediary companies?

Because of the intermediary company, he can't completely achieve satisfactory results in some places.

First of all, our personal preference is often not fully understood by the intermediary company, so the products he recommends sometimes make us dissatisfied.

Secondly, some recommendations of intermediary companies must have buried some pits, and they were accidentally pitted.

Finally, if it is an intermediary company, he will always make a difference in it, which is still not cost-effective.
