Russels should not be linked to Joshua door

Russels changed my delivery date for goods from 6 August to 12 August. Why? I had to cancel all my plans to be at home for delivery, just to be told it is not being delivered. I ordered online. The call centre team is rude and unhelpful. This is my first confirmation I received from them. "Hi Evelyn Barends. We will be delivering your Russells order on the 2024-08-06. Someone needs to be available for receipt. To change the date, you can call Customer Service on +***5. ***."
