Academy Brush dont give a damn

I bought the roller and brush set as recommended by Mica Bedford centre. The roller frame has hardly any thread and the nut un*****s while you are painting and the roller lands on the floor ...,a BIG mess, three sets...identical problem. I have tried to contact the company via the recommended email address "***" and got a email address does not exist. I find many companies that don't understand their consumers or customer care have these invalid email addresses. I will not try their products again...and for the record I am a maintenance contractor. BEWARE of this company
