and rightly so
fancy asking questions on a sales thread, your just supposed to buy it. end of. if its not right tuff luck
banes me that you have to buy something outright before you can ask any questions etc. should be able to register your interest and then ask your questions, if the deal or item isnt right then move on.
a few times i have been gazumped when trying to collect information, its not like we are stood in a shop and can see it is it.
i personally couldnt see any problems with your enquiry, find the ban a bit harsh. have you upset someone at sometime?
