Online services is horrible very bad

I think I'm complaining for the 3rd time & still there is no progress in your service, your treatment is horrible.I will never buy from Leroy Merlin. I have been buying from Leroy since I started my building project in October , and it's been hard, Everytime I need items to be delivered, or my refund I have to first complain, WHY?? Or I have to go to the store to get help. WHY? I've been calling everyday following up on my delivery but nothing is happening , it's been 3 weeks now. Urgently deliver my PVC ceiling and urgently replace 1 box of broken tiles, the courier driver reported about these broken tiles but nothing has been done.
