Buy & Get Promotion

I bought a fridge in December during the promotion and was called by samsung to say that the till slip is not clear and that i should resend. I did resend the slip and to-date I have not heard any response.<br> <br> I have made numerous calls, phoned them and no-one seem to take me serious. Can someone get back to me with an answer, else I am going to escalate this to consumer complaint.
