Rude Vodacom agents who do not know how to activate my SIM card

I’ve been having the worst experience with Vodafone for the past week. I ordered a router, they delivered it to my house, the next day they delivered another one (incorrectly as I only made one purchase) of which I rejected. Now I’m in possession of a Sim Card that is not activated. I’ve been calling their contact centre but I’m coming across rude agents who sent me from pillar to post and hang up the phone. I think 3 agents hung up on me at this stage without resolving the issue. I think they do that because they don’t know what they are doing. Worst service I have ever received. I wonder what I must do with a non activated router since no one has contacted me since it has arrived & when I call they cut the call. I’m not pleased at all. Do not order anything online I tell you!!!
