Every Step Calculus

I sell hundreds of these programs without complaint, all over the world, It is programs for calculus that they load into their ti 89 titanium calculator and it shows the customer step by step how to do hundreds of calculus problems for their tests and homework. This person would not tell me what was...

wrong with the programs so I could fix them or correct them, He was not reasonable. I felt he was not truthful, and wanted to use the programs (once loaded they can't be returned) and yet get his money back, they are 100% guaranteed to work., and do work and are actually amazing in their design.

Review: Mr. [redacted] promises on his site that his program will help you pass exams but his program is not complete. Many of his programs come up with incomplete or incorrect answers. I asked Mr. [redacted] over the phone and e-mail several times that I was not happy with his product, per his statement on his page, his program is 100% guaranteed or your money back. I have made many attempts to contact Mr. [redacted] to have my money refunded but he is not contacting me back. I want my money refunded pleaseDesired Settlement: I want a refund for a product that does not do what it says is supposed to do.
