I took an upgrade in February I wasn't receiving full benefits I called every month they was no help they captured the incorrect package. Last month I called again to explain what was going on the agent got someone to call me so they can sort the contact out. The agent contacted me so she took out a contract for R199 for me. I checked my bill for this month it's R637.02 .I called customer care to explain what's going on the response was I need to pay it.
