Bad service from Game

I bought a 10 lt pressure cooker from Game.2 months down the line,I find the pressure is not working.I took it back to Game.Few months later,it gets returned,informing me it has been fixed.When I eventually opened the pot,I found it wet in side and a bit rusted.The packets that was inside the box,still in the same condition as I have returned it to them.Game has never send my pot to be repaired.Im mad as he'll.I have paid a lot of money for the pot.
