I do not think all the problems we experience are always the companies fault.
It can be due to our having little or no knowledge to that of the companies who aften assume we, their customers know more than we actually do.
I'm afraid that even doing yourself can be a very slippery slope as there is so much we have to learn and sometimes just do not know what questions to ask. Even if you are supplied with instructions a small lack of understanding can lead to problems which could not be envisioned by more knowledgably people.
It would be nice gabi69 to know where you are situated!
