Vodacom still not helping

I reported Vodacom to hello peter in August after experiencing endless problems with my blackberry, they took in for repairs countless times but the phone is still not charging! I took it in again to The Grove mall and fetched it this past Thursday, guess what???!!! I still don't have a phone! its still dead and refuses to charge! mind you this stupid devise is still on contract but I am not using it!, I pay every month for a product I do not have or able to use, they never have phones to loan me, they refuse to grant me an early upgrade as I'm due in may! in the mean time they keep debiting my account every month but I have no phone! I have never been treated so poorly by a service provider, Vodacom has no regard for their clients, its been over a year and I have a the same problem over and over again and no one gives a damn! I booked the phone in again yesterday in Menlyn, I know how this is going to turn out!, they are going to update the software or give me another devise that's not working! They are just happy to debit your account every single month without fail! I am fed-up and will never purchase anything from them again! Give me my money back and take your stupid phone PLS
