Dissatisfied customer service

I have been trying to cancel my home router contract, I called the vodacom call center they kept on switching me to various departments without helping me with my issue so today I decided to go to a vodacom store maybe I might get help face to face, so I went to South gate vodacom store explained my proble to this lady and she told me I need to call, I told her I've been trying to call but I don't get help and she said I must call again and she left me there hanging. I am very dissatisfied with their customer service. Even now I am not helped
