Still awaiting delivery for online purchase

It has been a month since I placed an order with LeroyMerlin online and it is yet to be delivered or may be never. A month later customerservice staff have not responded to my multiple queries. This is not an isolated incidents it has become a pattern by LeroyMerlin it will be the second time I experience such arrogance, incompetence staff and such inconsideration towards a customer. LeroyMerlin online is a total disaster and failing its customers you should go back to the drawing board to figure out how you could get it right because so far you are getting it wrong. Your online service is pathetic so is customer care service and staff with appalling attitude useless individuals who have no care in the world about the need of the customer as long LeroyMerlin rip us off our money you feel just fine getting your salary . Shame on you.
