BIS Connection not working

My BIS was working perfect. Phoned Customer Care on 26 Sep to ask if R59 will be deducted as per normal. Dion said yes but he made changes/deactivate/activate to my gprs and apn and told me to reboot. Since reboot my BIS is not working. Vodacom just gives me the run around and not solving the problem! It is now 19 days!! Vodacom says that the BIS is active BUT my Service Status on my Blackberry says BIS NOT CONNECTED! My BIS is not connecting/working.<br> This is now unacceptable service. I cannot even use the once off data bundle on whatsapp or FB. I can only use the Internet Browser.
