I bought their software to fix an issue with starting Windows 10 on my Laptop. I contacted the customer service because I was not able to start their software from USB pen. They provided me a generic solution, which did not work. I contacted them again, explaining more in detail the issue and attaching multiple pictures of the error and steps to reproduce it. Then one month of silence, no replies. Contacting them again they provided a link to download the software for Windows 8 64 bit, no sense reply, not related to my issue, also because I have windows 10! After complaining again, they told me to send Windows product key sticker so that they can provide original Windows CD. To recap, from one issue they provided no sense solutions. At the end I fixed the issue myself after 3 months of e-mails. Wasted money.
