Billed after complaining 5 times about my bill

I received my bill of R 1,337.55 when I upgraded to a contract of R 680. Billed for x2 handset due at the end of November and my bill so far also has a handset installment?? I don't understand why I have to pay for 2 handsets when I have upgraded. I'm tired of contacting the call centre because they cannot help. I'm tired with dealing with Vodacom. You should let your customers know how this works. You advise your customers that they are legible for an early upgrade but do not mention that you have to pay for more than 1 handset!

Not only am I being billed for 2x handsets, but SMART S + Line Rental X2 as well!! Why??????

Surprisingly I was billed for the Promotional My Gig 10 - 1 Month, but credited. That was not a mess up. Who works in your accounts department? Because it is clear they do not do their jobs correctly. I'm am beyond frustrated, and need this to be sorted out asap before I have to deal with arrears for not paying!! my next months bill should not have any more errors. It already looks like there is an error as I can see what I'm being billed for,
