Bad vodacom service to committed clients

Good day I am a vodacom customer been paying well on smartphone contract deal in 21 March I was called by vodacom to upgrade they offered me new line deals and 2 devices I agreed took the upgrade I waited for about 3 weeks waiting for delivery while they advised me I will get them in 3 days time then I started wonder what is the problem as I didn't receive my devices but the line has changed to the deal of an upgrade then I called vodacom on third week they advised me that my devices is with ram they've been attempting to deliver with no success that when the consultant told me to call ram and check with them after she gave me tracking number on call after 3 weeks when I call ram they say vodacom gave them wrong address even vodacom agreed the address on package is not address on my vodacom profile on their system thats where i suspected ***** as even ram told me i nominated someone to accept my delivery even the number on package was wrong not even the same as what vodacom have on their system phone number reason they failed to deliver and they sent them email to approve my address till the devices was sent back to vodacom warehouse I called vodacom several days till the fourth week everyday to resolve these they end up blocking my number when i call them they say the escalated matter to back office sometimes they confirm with ram i will get devices following day but tracking number on website say something different as my parcel has been shipped back to the sender now my bill on the update is R2048 including the upgrade I did which I don't have the devices n before these upgrades my bill was only R688 now I can't call them um block I don't have the devices but I have to pay that money there's no one even calling me to update me what next
