Dartshopper delivery issues

Hey, has anyone ever experienced the same stupid dartshopper delivery issues as me?

I´ve never ordered anything off them, and i decided to do for the first time without reading any reviews or anything, simply because they are a big brand and because they were the only shop who had the stuff i wanted in stock. The fact that theyre advertising their quick delivery (shipped on the day of ordering or the morning after) made me pretty confident about it as well

However, about 4 days after nothing has changed from the "Picking it right now" order status, i started to be a little angry and sent them a message. The same day, the status changed to "shipped"
However, when you open the tracking link they provided me with, the DPDpl status only shows "Registered parcel data, parcel not dispatched yet". It´s been 3 days since.

I find this absolutely crazy, that one of the biggest brands on the market can have such issues with sending a single package for a whole week, when they have promised it to ship next morning latest.
Anyone has the same issues?
