Waterfront store doesn’t take accountability for expired food

I went into the V&A Waterfront store last week. I wanted soft food for my dog who had just undergone surgery on his mouth. The assistant offered me a product at 50% off, saying that it was a “slow seller”, but should my dog have an adverse reaction to the food that I could return it to any store and get my money back. The following day I contacted the store as I saw that this product expired in October. The assistant was apologetic about the inconvenience etc. I then asked if they could collect the food and bring replacements since I had driven all the way the previous day. I was told that someone would call me to confirm. They did - I gave my address and my husband’s contact details in case I wasn’t home. No one came to collect the food. Not a call to say that no one would be coming. The following day I took the food back to the Cavendish Square store. The assistant called the Waterfront store - another apology saying they were very busy. Too busy to call or too care. Customer Service is what keeps the customer coming back. It’s called respect.
