Never never register yourself in seventymm for rental movies. I got money back from seventymm after lodging complain in consumer forum. Every consumers are requested to lodge a complain in consumer forum against them. It is simple and enough to punish them.
Don’t waste time by requesting to their consumer support personal. Before that you should preserve all the documents i.e. cash memo, e-mail or any correspondence. It is absolutely free of cost. Hope this letter helps a lot for the consumers.
