Still don't have my order, it's a day later

I placed on order on Tuesday and received confirmation that my order will be delivered on. Friday the 1st. No delivery, no word from Leroy merlin or the courier guys, apparently they collected the hob from the store and someone is sitting with my order and I'm being told I'll only receive my order on Monday. What nonsense is that. I mean if you promise to deliver on a specific day, do that and ensure that that is done. I'm on a call with someone in the call centre now for over 30 minutes, imagine how much this call is costing me. I wouldn't recommend Leroy merlin to anyone
