Bought an micro-SD and was damaged when opened

I bought a samsung 8gb microsd and noticed it was cracked and broken . I went back to the shop immediately and they refuse to refund or replace. It was excuses they have to phone the supplier first , but then mentioned to discuss it first with the regional manager and i'm not allowed to have the phone number .<br> <br> I already cancelled my contract due to exceptionally bad service and will now probably have to opt for another network as I don't want to spend any money with them as this is obviously how Voda employees think they can treat paying customers . <br> <br> The packaging is also extremely excessive and no way to tell if the product is ok before walking out of the shop
