We signed up for a deal that comes with a router, they provided only the sim card, they said the router was out of stock, few days later we got the router, however it's not working went back to the store they said the sim card was faulty, they gave us a new sim card we were advised to go home they will contact us once the sim card has been registered, they did call and said the sim card is registered but the router was still not working, one of the ladies came to my house to check the router she also said the new sim card was faulty as well and she gave us a new sim card advised that it will be working today morning, today morning the router is still not working, I called the store and they asked me to put the sim card on my phone I did that and the sim card is still not reading and they advised that they will call the service provider and get back to me but still they haven't called me yet I have paid for everything, their service is just poor why would they have more than 3 faulty sim cards... I'm really not happy about Vodacom, I actually want to cancel this whole thing.
