poor customer service

I bought cheese in April and a day later it had mould on it, I called customer , service, spoke to numerous advisor and even the manager at canal walk whom was suppose to get back at me and never did I do not believe they have just let go like this!!!!! I was constantly busy at work and they attempted to assist and they never even told me my case was closed my child got sick and had to go to the doctor due to the consumption of the rotten cheese, the level of how my case was handled it very appalling I still need the issue to be resolved.
