NO CONNECTION ON PHONE

I had my simcard in a Samsung. On the weekend my phone was ****** so i had to put that simcard in my old Blackberry. I've loaded the BIS services on Saturday morning. It is now Wednesday afternoon and still i cant use my phone. I can send and receive BBM messages, but i cant download whatsapp and go on the internet. Then i get a message I dont have data plan. I've phoned them so many times, and last night 2/2/2016 a technitian was suppose to phone me. It's now 12 hours later again and still no one has phoned me back. Do Vodacom really care about their clients or not??? Cause how long must a customer wait to get a service you pay for. Its empty promises all over the show.
