WONT GIVE REFUND

Got cot mobile I February and it stopped working about 6 weeks later.went to change it, NOT FOR A REFUND, and rude sales staff and manager insisted on a till slip and box. This as a gift, and I WILL NOT ASK FOR A TILL SLIP WHEN I RECEIVE A GIFT!! They sill had them on the shelves, and I know it was bought from there, as I had told my friend to go there to buy it. The area manager said it was their policy, and didn't care who I spoke to. I contacted the ombudsman for consumer goods, and after a lot of emails, they told me there is nothing they could do, despite there being nothing in the act that says you have to have a till slip. I will never set foot in that shop again, and am telling everyone of my experience (take a look at all the complaints against them!) and am equally disappointed in the ombudsman. What is the point of him being there if he cant or wont do anything!!!
