Vodacom ****ming their customers into upgrades

A few months ago I upgraded 4 of my lines. I received a call 3 weeks ago from a Vodacom call centre where a woman told me that she was sending me routers because I upgraded my account. A week later after I received 3 routers Vodacom mailed me a new quote. I called customer care and discovered I was deceived and this woman up-graded 3 of my lines again! The customer care agent put me through to ***. The agent at the upgrades call centre assisted me and said he was booking a courier to have the routers collected and once collected these 4 up-graded would be cancelled. It is 2 weeks and 3 follow-up phone calls from me later and these routers have still not been collected and these upgrades have still not been cancelled. I am not getting any support from Vodacom and it feels as if Vodacom is condoning conning their customers into upgrades
