Shocking quality of goods and shocking service

I spent R 9000 on an outdoor suite. It arrived, but all the chairs were damaged and no one chair matched the other. The table was also damaged. With no contact from them I heard from the supplier that they were replacing the set. The second set arrived (aluminium) and is covered in rust. I thought aluminium does not rust. No feedback from the Leroy Merlin. Then against my better judgement I purchased lanterns. two weeks after placing the order I contacted them to be told my order was out for delivery. three days later I receive an email to say there is no stock and I will be refunded. When emailing back there is no response and I still have not been refunded. Im not sure how this company stays in business but I will never purchase from them again nor would I recommend them. There service delivery and in house service is shocking to say the least.
