This holds true in my case as well. I bought a Samsung STAR mobile for 10K last year(Aug 09) in mansoon Offer. I chose ebay gift as Transcend portable Hard disk(320 GB not sure about size) which never reached me till date.:(
Same reply from customer care executive.
I also mailed, complained numerous times to get the free gift. actually this gift was one of the main reason I buy the mobile from Ebay.
Now I have stopped replying on any special offer and limit my buying.
Thanks for (at least) reading it till end,
Tarun
