Disc Cutter

I brought a Indian disc cutter from a well know jewellery tools site, what a mistake, not only do u have to hit the thing 500 times to get the got dam disc out , but they come out all mangled and with rims on, so I ring up to complain only to be told not only do I have to pay postage to send the thing back, and its heavy, but they will inspect it and if they think I have damaged it, I havnt its just rubbish, they will not refund me. Are they taking the mickey or what. Word of advise don't buy a Indian cutter spend the extra money and buy the more expensive ones :0(.
