Transportation costs of the goods that has a factory fault

I bought a coffee table online and collected in store (Pavillion) I couldn't assemble it because it had a factory fault, I called the store they said I need to bring it back they will assemble it for me so today I took it back and only found out that they all knew that those coffee table has a factory fault they can't even exchange it. So the manager said I must contact the online people for my refund of which I did that and they said they can only refund the coffee table but they are not paying for transportation of which I hired a car to take the coffee table back. I am so unhappy about your service and I need a refund for transportation, I asked them to come and pick it up and they refused because I collected they are not the one who delivered the coffee table for me
