OTTO delivery time change?

I ordered a gaming lap top from OTTO a few days ago. When I ordered this there was delivery time 4 weeks. I checked the offers again today and now I have delivery time "tomorrow at your place" or something. In my account delivery time is still 4 weeks. Do I really have to wait 4 weeks now, even though I ordered earlier, or will I get it tomorrow?

Cancel or order again…

And if the other still hasn't come, cancel

Thanks in advance. Unfortunately I have already transferred the payment which is why I do not want to cancel. LG
