Poor delivery time and no response from management

My online order stated the correct delivery address, but Leroy Merlin gave a different delivery address to their courier supplier. This happened with two separate orders. It took up to two weeks to get the products delivered after many phone calls and emails. A total nightmare and very frustrating. The online website is also full of errors. You cannot add a billing address and you cannot track orders. Although these options are provided on the website. it simply does not work. I asked for senior management to contact me, to date I HAVE HAD NO RESPONCE.
