Poor Service/No delivery

I made an online order on the 25th November 2022 which was for a LED rechargeable lamp and Nike Junior Air Max Dawn Sneakers (order no: p***) however only one parcel was delivered on the 29 November 2022 which was the lamp. I am still waiting for the delivery of my sneakers and I have sent them an e-mail and I haven't received a response. I called TFG online queries on the 03 December 2022 and was promised that my parcel was with the couriers however I should have received the parcel by now as it was supposed to be delivered on the 05 December 2022. I can't even track the status of the delivery with the tracking number. I don't even understand why no one is getting back to me. I have to be the one calling in and sending e-mails. Can someone get to me asap as I'm expecting that delivery this week.
