Please dont call and give my numbers out

I received a call from *** 10:09 on my cell number and a guy tried to sell me stuff as a vodacom affiliate. He insisted in me giving him a delivery address and advised that my contract amount will decrease. he had all my details and credentials that i have entrusted vodacom with, he knew about every contract option and every device i had. If vodacom didnt give him the details as he advised it means he stole my details. please could someone eighter remove me from the list when u give out telesales leads or investigate this breach of your clients details because i know im not the only one.
