Bedita, I caution you to avoid this kind of personal and libelous attack. In particular please note the following excerpt from the Forum Rules:
From my point of view your attacks on Mario seem intended to do exactly that, harm his business, and it won't be tolerated.
I'm not sure you can classify it as "personal and libelous", especially if bedita can prove his allegations.
If Mario has not refunded his/her deposit, then as Bedita claims, he is simply lying.
