Visa Revoked by Italian Consulate in Dubai

You have 60 days from refusal to appeal.  This is filed with the Administrative Tribunal in Rome.  I am not sure if any lawyers in Dubai will handle this but on the internet, you can find a lot of Italian immigration lawyers based in Italy who will handle these cases remotely.   Giambrone is a good one from what I have heard.

I don't think you will be banned but all future applications will face increased scrutiny. 

In terms of advice, if you are applying for a tourist visa (and not business), don't have a history of travel to the schengen states and then add your family later; it does look suspicious in their eyes.  It makes sense for business visitors to add family later and do a holiday at the same time (but not the other way round).  Not saying your intentions aren't genuine.....merely that it is a red flag especially if your nationality is from the sub-continent area or thereabouts - as a lot of people follow this mechanism for illicit purposes.  Also, I don't think you were able to explain your intent very well in the interview - as while I have had this happen to some friends of mine; their visas weren't cancelled because they were able to show evidence of intent.   

Remember, in case of any doubt, they will always reject or cancel - doubt is created when your answers are not convincing or consistent.  Also, if you pick a fight with the visa officer or get angry / evasive in your responses, that also doesn't go well.
