Questionable Online Service

I placed an order on the Nespresso online store , got told del is 1-3 days on the 29 Nov. Nespresso courier company is Courier IT . Driver dispatched next day with my parcel, im excited and guess what ,the start of my nightmare experience. 1 day becomes 8 days later still no parcel. Each time on the tracking of courier driver dispatched just to be taken back to their hub stating customer not available. I confirmed with my security and reception nobody from Courier it arrived thats backed up by camera footage aswell. So where is the courier going to or not bothering to dropoff. No calls to find out or re verify if this driver is lost nothing of the sort. I have everyday for the last week called into Nespresso clubs call center for assistance verified all my details address everything. Each time I get told that my query is been escalated ! and guess what nothing happens . Their call center are very polite and come across as professional but this doesnt help if you cant remedy a situation now does it?. By yesterday 6 December I had absolute enough , it got to a point where it was sounding promising as I was told again its been escalated but to both Management of courier it and Nespresso and a same day driver has been dispatched, as my parcel this time wasnt even lodged to a driver for delivery. You know my next statement no parcel , no sameday day driver no followup call back after i was told by the agent they would. Sort my parcel delivery at no cost and kindly have your CEO of Nespresso to give me a call .
