3 CS numbers, 3 parcel tracking numbers for one lost item and Nothing

Dear TFG ,

I order goods from @Home Online on the 19th of November. 4 of the 5 items arrived to me on the 22nd of November, and one large item wasnt included. From the 22nd of November, i have been calling your customer care, every single working day day, and 3 times i have been given a different tracking number because the item was found and is being shipped to me and none of these tracking numbers exist at all. Twice i was told that i would get a refund; how if the item is stilll available?. I dont know how this refund is to even to arrive to me and when. My CS number has changed 3 times, i dont know which is which at this point. On Friday, one of the online customer care managers whose name i can happily supply responded that he will write me an email on the real status of things, and even though i followed up to request an update, he has not done so. I sit here, with no refund, 3 CS numbers, 3 tracking numbers; essentially i am being sent from pillar to post.
