Baby Hamper

I was contacted on the 19th of October 2015 to tell me I was entitled to a baby hamper and asking for some details. I responded with my details but never got the hamper. I emailed asking if there was a problem and again was asked for my details, gave them again but never received the hamper. Emailed again and was told it was delivered to a different person at a different address. Wrote back telling them they had delivered it to the wrong person- no response. Wrote back again telling them that they had delivered to the wrong person and that I have never received my hamper, they wrote back to me telling me it had been delivered and gave the details of this other person at the other address. It's 14 weeks since they first contacted me, I have yet to receive my hamper. I am obviously a new mother and getting very tired of emailing again and again to no avail.
