No I don't wonder why you have a problem with me. I used to be just like you. Nor do I wonder about those others either. Remember that I reply to what y'all say, not about you as to what kind of person you are or where you live or how you live.
Your instructions were not included and my mistake was thinking you would have sent them to all your customers if they wanted them or not but... me, I wouldn't sell to anyone that refused my instructions or if I had the slightest idea that they wouldn't follow them.
And as we see, the OP has had many questions. Many of which I would have answered before he bought from me because I know prospective customers usually don't know enough to ask questions about everything they will need to know. I even had them write down programing info and the data before they bought from me. And asked them if they had any questions about that. Some of those people I educated didn't buy from me, or then but came back in days to up to a few years later. I talked to every internet customer I sold to.
I also I notice that your customer was interested in me answering at least some of his questions... That alone should have got your attention but it seems as if it hasn't. Or, you too were relying on me. I usually smile while typing replies but now I'm grinning pretty wide over that.
Tntent, you're welcome.
