Leroy Merlin Circus Runaround

I purchased an item from Leroy Merlin in Little Falls. It was delivered to me in Benoni. I wanted to return this item but it was too big to fit in my vehicle. I decided to approach Leroy Merlin Boksburg with my issue. They refused immediately and mentioned "We only deliver". I said no problem, I would get a courier to deliver. They said but the courier must deliver back to Leroy Merlin Little Falls. I decided to visit Leroy Merlin Little Falls to make sure this is ok or was the right thing seeing as I live in Benoni. They said you can deliver to Boksburg as we are the same store. I booked a courier to deliver to Leroy Merlin Boksburg. I made arrangements with a staff member and a manager at Boksburg for this return. The courier was sent away 3 times and eventually no manager at Leroy Merlin Boksburg wanted to accept the item. They now say I must send it back to Little Falls. So I initially paid the courier to deliver to my home. Now I paid the courier to deliver to Leroy Merlin Boksburg and now that they refused the item, they want me to pay the courier to send it back to Leroy Merlin Little Falls? This is absurd. They are one store. They're systems and managers are pathetic and the people in charge are too lazy to handle situations Why can't they accept it at any Leroy Merlin. Why did Leroy Merlin Boksburg give me the run around. There is always a cost and it always falls on me.
