call limit not working

Hi,

I have a 24 months contract with vodacom( ********** 669), which they provide 500MB for R45.00 I have asked Vodacom to set call limit of R50.00 on this contract, but yet this month my bill is setting at R1005.80. I did try to call Vodacom about this matter around mid August and I was told at that time they can't tell where the billing is coming from, and must wait until around 4 September with bills are finalised.

I believe that call limit are there for a reasons to set not to go above one's affordability. I don't understand why Vodacom is fooling us by providing functionality that randomly works. I am saying this because Last time i was told that call limit is not guaranteed but surprisingly this only applies to so called the best network(Vodacom). I know for a fact that call limit works on Cell C, Telkom, and MTN contracts because I have their contracts.

I am so disappointed in Vodacom and can't wait for my contact to end, comes December to Determinate it.
