Vodacom - abusing customers' rights!!!

I have had my Vodacom cell number for about 15 years. Last month they terminated it because they said that a ***** has been committed on it and the number was subject of a ***** investigation. They were unable to say how long the investigation would take . I was told that I could not talk directly to the ***** department and I had to wait for them to complete their investigation. I now have to get a new cellphone number and inform all my contacts of my new number.

I was given no warning of the suspension and my accpunt is paid up to date..

How can any provider be so uncaring of their customers?
