first they mess up the upgrade and now the bill

I called Vodacom to complain that i am being charged for 3 Handsets when i only have 1. They have said that it will take accounts department +- 7 days to come back to me regarding this. Not great customer service<br> This is the 2nd month i have paid for 3 handsets. Why can something not just work after it was complained about on Hello peter previously. Surely if they know you are unhappy they will make sure everything on your account is 100%<br> REF:S3-90E2I-IC1S7
