Bad and terrible service

I am so disappointed in vodacom. I’ve been a client for so long (years & years). Recently they advertised an uncapped contract for R499. I app**** & was approved. Got my router and started using it with no problems. Last week it stopped working. And nobody seems to be able to help me. Now I’m paying for something I’m not even able to use. I am so annoyed to say the least. I am highly considering leaving them. More so before I get another contract for a new cellphone.
