Heater that will arrive in summer

Bought Alva heater from Alva on the 10/06/2024 and apparently it was supposed to be delivered on the 19/06/2024 - I don’t know it’s taking this long looks like the product will arrive in Summer by the look of things… poor service by their service desk, lady said it’s no longer their problem that the product it’s taking so long to get to me. They sent the item using internet express courier. This is the slowest courier experience I have ever experienced.
