I bought this cake serving set online last week but accidentally it has turned out to be defective. I have contacted the store and they have totally denied to take irresponsibility of it and replace it as they say are showing proof that it was fine when it left from there. I am stuck with it now and have become hopeless for a solution as I have tried every possible way I am aware of. What options am I left with now? Is there is anything positive that I can hope for?
