Redeeming a voucher

This company is a ****. We went there for a presentation, tried to register a week later as they advised us to but it says the voucher does not exist. Tried again weeks later, same result, called the lady who called me initially but still could not be helped.

These people are just wasting our time, I've never met a single person who got successful with this. Do not even bother yourself, total ****!
