Very Disappointed in Product and Refund Policy

I purchased software from Tenorshare which did not do the job. They advertise that they will refund the money if one is not satisfied, this is met with a support person that tells you that due to misunderstanding the product, and not a software glitch they will not refund the product. But now I cannot get a refund due to this. Tenorshare appears to be dishonest and not clear in communications, and I will never use their products again.
