Black Friday ****

I bought a pair of shoes on black Friday 23rd Nov. I checked my delivery online to find the order cancelled by tfg. I immediately called the call Centre and was advised they cancelled my order due to stock issues and technical errors in there system not picking up they no longer have stock. I requested a manager twice and was transfered to normal agents that did not care about customer experience. I want this item at the same price as advertised or I will take this matter further. This is poor customer service. You are in breach of contract as me buying this product was all in order. Honor you agreement and get me the product I want at the price I bought it at.
