Vodafone's decision not based on facts !

Due to deactivation of my number, people I have given my business cards to would naturally think I gave them a wrong number because they are greeted by the message " The number does not exist !". Because of the unfair action of Vodafone , my image in the work field is getting affected. Vodafone had no right to deactivate my number without an investigation ! Vodafone cannot get away with this ! They should be not allowed to humiliate customers like this.
