Vodacom Playing with my money.

I made an insurance claim in February for a home router device, they couldn't repair it and told me that I'll get a new one. But they sent me a router that doesn't work. I returned it again... They expect me to pay excess fee again. Now it's April and I'm still waiting. I'm loosing out on the data that I'm paying for every month on my vodacom contract. At the moment I'm forced to buy data everyday since their simccard only operate on that device. It's too much, it doesn't even deserve my rating at all.
