No customer support

The support here is ridiculous. They ignore your requests for weeks then come up with a simple question like “do you use diagrams?”. Although your question was about you using diagrams and in the attached files are diagrams and you clearly stated in your request that you use diagrams.
Funny thing is that after you patiently answer “yes”, they disappear for another week.

Last but not least, after I purchased the product they stopped answering at all!
I have now a couple of outstanding requests and there’s no answer for more than a month.
If the Spreadsheet Converter team sees this, please, I beg you, contact me.
