Why must I pay for no service

In January I reported a problem with my fon router (second one in a few months with same issues! When calling the customer line I was told I would be contacted within a few days, then nearly a week later I get an sms stating my router is on its way. A few days later I receive another sms starting oh sorry we don't have stock available this after a confirmation msg stating it's on its way??? I then phoned the customer line and then get told I just have to wait, after a what seemed to be forever holding period again I get told maybe I'll get one end of February maybe later? I then get told to use another router? Where must I get one? Now I need to buy one due to your poor service delivery!! Why must I waste my own money to assist you when I am the customer! My account is already paid yet I don't have service? I can't go to a mweb store either to collect one as I was told? So how do they then open new contacts as these routers are included in the contract? After nearly a month I still haven't received any follow up with my router? How do you expect to service people without the equipment? Be ware of the contract as you will pay for service you WON'T get!
