Disappointed in Adidas Online store

I placed an order on the 18 November 2022, after a very long delay on the delivery I received the package on the 5 December 2022, upon opening the box I realized that there is a missing item a white crop tshirt, I immediately contacted Adidas and was told by the consultant to send an email to Adidas to report it. I did just that, up till today still no feed back regarding the missing item or what there solution will be whether I Will be receiving the tshirt or a refund. I can honestly say I've been ordering from Adidas for a while and haven't experienced this delay in delivery because they used dawn wing courier company never had any issues with them, since they have been using courier it wow I've been very disappointed, courierit sends a notification to say your parcel is out on delivery on the said date then you only receive it a day or 2 later because apparently they give it to a third party courier company to deliver, the vehicle it gets delivered in looks like a jikeleza vehicle. Call center experience very very very bad, I hate it because it's like these people answering are robots like they have been programed by a computer. Whoever is now in charge of there online sales is really failing the customers and a huge change needs to be made to put their customers needs first AGAIN. I love Adidas but there online store for sure sucks.
