Vodacom

Hi vodacom, I had a bad experience in one of your stores and the treatment was not satisfying at all. My cellphone got ****** it have both vodacom Sim cards I've received from you guys and the phone is insured. A strange thing said in store that I cannot be assisted bcz according to them the "Sim cards were not active as from last year". I've been using the Sims ever since I got the phone so must I do now. You expect me to continue to pay for something I don't have?
