Terrible Customer Service

I purchased a shelf company from Company Partners and was led to believe the entity has not traded at all up until the day I bought it. After the purchase I tried to register the company for workman's compensation only to find out it had already been done previously and I'm expected to pay the arrears due to them not doing returns. I called the agent that helped me and was told sorry nothing they can do I must sort it out myself as I didn't use them to register. I explained that it wasn't an issue I created as the returns are for the years they had the entity in their possession to which I got told under no uncertain terms again they cant help not their problem. I purchased this entity for quite a sum of money and now to be told they wont help fix the problem they created is just terrible. Be very careful when purchasing a company from them as there are hidden issues they don't tell you about.
