Wrong billiing being ripped off by MTN

I originally had 3 cellphone contract with MTN and recently i have terminated 2 and i m left with 1 that is sponsored billed by my company. I just opened the invoice that i received and much to my dismay Im so not impressed with the money that Iam gonna pay this month the bill says i have to pay R620..How is that possible?? And i have an iPhone but they a deducting Blackberry internet service... Like really you people like ripping people off under false pretenses hey... Please fix this and I need my money back, Im supposed to be paying R200 not R620
