One of the best malls for the Hyderabadies near by Tarnaka/Uppal etc, but unfortunately there is no monitoring of who is collecting the visitors phone number and where is that data base going. I visited DSL uppal on last sunday and Today I received a call saying that i visited the mall and my phone number won a prize. I did not expect this from a classy mall like DSL. what if this data base of phone numbers goes to wrong hands, Need immediately action on this for the best interest of the diginity of the mall.
