Delivery support sucks

I ordered an item onlne on friday 2026/4/10 They then send me an email that delivery will be on Saturday 11/4/26 and they did not deliver. I then waited for the actual delivery date that is today 14/04/25 and nothing. I phone them and they say they can only escalate the problem. I had to put in 2 days leave just because they dont know what they are doing. How long will it take for me to get my paid in fulle order? They dont even contact you and give you updates
