Broken promise to deliver

I am expecting a parcel and on Tuesday I used the self service portal to select delivery for 07/03/2025. Later on an agent override my date to the 10/03/2025. I explained that I selected the 7th. Later on that day I received 6 SMSes from CCD confirming my delivery to the 7th and I was happy with that as that was what I asked for initially. Then today on the 7th I called in to find out what’s happening because I didn’t receive any communication confirming my parcel is out on delivery and to my surprise the agent says delivery will be on the 10th. I asked him to put me through to the complains department cause I need a same day delivery to be arranged as per sms confirmation, the agent escalated my matter to their supervisor and a same day delivery was approved and I was told I’ll receive a call from the team that deals with same day deliveries to arrange. I received a call from a lady (forgot her name) she said delivery will be between 14:00 and 17:00 and I asked if my mom who I stay with can receive it on my behalf she said she’d call me right back she wants to confirm. 2 hours passed without the call back and I called CCD. Tammy answered my call and she said she can’t see anything for same day delivery my parcel is coming on the 10th. I asked her to go through today’s notes cause there should be something on system. She said it might be too late to arrange for a same day delivery and I pointed out to her that I called them at 08:00 and was promised the same day delivery, that should be enough to make arrangements as promised.

I’m so disappointed in CCD
