Vodacom fibre worst customer care

I app**** for fibre package and got approved in November. Vuma installed 2 weeks ago and vodacom fibre still have not delivered my modem. I can also not collect it. After endless calls and new service request nrs i decided to cancel subscription and was told to email it. I did. Have not received any feedback so called again and my subscription is not cancelled yet although the guy told me someone opened email yesterday allready. As for now i dont want to go to another service provider until this is resolved but doesnt seem like they take action until a review is placed!
