Here is my answer copied (for you) from the other post;
1--You asked me to turn on the error reporting while already telling me this is VM problem and outside of your support , therefore already assuming I would pay for extra support to fix issue that was started the moment your component was installed.
2--I was done responding when I found out about your idea that I would pay for support to fix an issue that was started with installation of your product.
3--THIS IS WHERE MY POROBLEM WITH YOU IS: Since you sell a component that creates and sends invoices to customers, it is logical to assume that it would not make the customer receive 2 different invoices (one from your component and one from VM itself). If in fact that is the case you should INDICATE SO in bold letters to people that they must edit VM Code in order to make it work as everybody thinks it would. But that of course would hurt the sales right?? Look, I know your strategy--once you omit this very important detail people will buy your component and then of course rather focus on paying someone to fix VM coide to stop other invoicing or pay you. You know it that's why you conveniently do not mention this UP FRONT! You can hide behind all your fine print all you want but a respectable seller would never hide this to make an extra buck. And by the way--you know I'm not the first one writing this, so dont give me crap that I am the only one here.
Kkeep the post, this way people will at least understand how your component works and how you dont mention few things in order to make a quick buck:
a. Your component will send just another invoice to customers, so they receive double the invoices, not only your componnet's invoice, instead of the VM one
b. In order to fix that (or the white screen that will screw up your checkout process), customers must either pay someone else to edit VM code or pay you to stop VM invoices being emailed out as well
c. the fact that you are still not embarrassed by your business management is just crazy and again, I urge everyone to stop and think before doing business with you.
P.S. There was never a business that was lacking in customer service as much as yours does. Be honest and UP FRONT with your customers about the shortcomings of your product...just an advice.
