[Skunkworks] Ripped off by orange - Did not get my double bundle!!!

I saw an advert in todays paper that indicated that if I load credit on my orange mobile I will get double of either data or sms or voice... I loaded my Ksh. 150 and then went to #123# and then went to the "promotions" menu and bought 100MB for Ksh.150... ...but I did not get 200MB (i.e. double)... I called customer care on 100 and they told me that Ksh. 150 is for 50MB... But looking at all their posters, the new bundle for Ksh.150 is 100MB...therefore I should have gotten 200MB if I bought that bundle!!! Therefore I urge you to note that the double thingy does not work for data bundles!!! Claire.
