Mazaya - Cairo, Egypt

I went to mazaya city center branch and i asked for an eyeliner pen ...the empolyer showed me a tester of l'oreal paris pen and it was very black and thick as i asked...then i bought 2 pens of it...and when i was back home i started using it then i recognized that the pen was very light and it was almost empty.....this is a shame on the name of mazaya stores but honestly i bought although pond's cream and it was good..

I received a gift from my freind bought from Mazaya and I went to one of their shops to change it because it does not suite me but they refused to change it because I do not have a gift receipt. I gave them the date it was bought and asked them to check on their system but in vain. I am wondering what I am supposed to do now with the perfume and why I cant change it even if I do not have a receiptt though they can get the proof on their system.
