Poor service

My account was transferred from Autopage to Vodacom because Autopage are ending their services. My debit order this month was suddenly more than double the usual amount (From R800 to R1750). Since yesterday morning I have made more than 6 phone calls to Vodacom customer care, nobody can provide answers or even tell me if my data bundles are still active. Im still waiting for Susan, the supervisor to phone me 3 hours after the time we arranged. I don't know who to phone for answers regarding my account anymore
