Dishonest Staff beware!!!

Had my number plates done was charged R290 for two number plates different sizes, one of their staff made by printing an incorrect sized number plate when he quoted me. (This I witnessed as they were fitting). I went to go clarify the charge and they were adamant about the charge, what upsets me is the fact that they charged me for it and carried on lying about it instead of just telling me about the mistake I would not have minded to pay. The staff are dishonest !!!!!!!
