Poor Customer Service

I had an issue with my router Vodacom S90 4G. I took it back to Vodacom, only to be told, they would take it for repairs. Now my issue is, that I work from home, and Vodacom does not even provide a solution as to what must i do while I'm waiting for the router to be fixed. They can't even provide me with another router in the meantime I was just told, there is nothing they can do for me. it's not fair to wait 3 weeks without internet and be expected to pay the full amount at the end of the month. I'm so disappointed with Vodacom. I only had the router for 3 MONTHS!!
