Unsatisfied customer

Hi. My name is Sithembisile i have been vodacom customer for more than 5years now, so since yesterday my phone it is giving me 'no service' message on the network point. Then when i called Vocadom legal department they told me, my number was deleted how i do not know,then i called the vodacom customer service they told me that they will respond to me after 7 working days.. Now i am not receiving any calls and i can not make calls or even receive sms's. I have used this number for everything including applying for my daughter at school.
