One of the advantages that Technobox offers is that it allows the customers to test the product before completing the economic transaction. The top manager at Technobox says: Yes, our prices are not comparable to other brands. Our profit & loss account might have negative numbers on the short run, but this will help us expel the rivals from the market on the long run.Hadi purchased an oven from Technobox, examined it at the point of sale, and received a warranty which stated that the oven is associated with a guarantee for ten days. A couple of weeks later, the oven stopped functioning, so Hadi decided to sue Technobox in this regard.On another note, the sales representative who sold Hadi the oven works for Technobox for 52 hours per week, and the company assures that this is a normal regulation since it already took the permission of the minister of finance and is paying him an adequate salary.
