Delayed order and unclear tracking information

I am writing to express my frustration regarding my recent order. I placed my order on Friday, and your stated delivery timeframe is 1–2 working days. However, it has now been several days with no delivery or clear update on the status of my parcel. The tracking number provided does not seem to correspond with any recognised courier service, which makes it impossible for me to track my order. This is very concerning. I would like clarity on the following: Which courier company is handling my delivery The current status of my order The expected delivery date If there are delays, I expect to be informed proactively rather than having to follow up myself. Please resolve this matter urgently. If I do not receive a clear update or my order within a reasonable time, I will have to consider further action.
