No service at all

Well to start off. I decided to use Vodacom as my ISP as they had a really good deal and I had had no problem with my cell phone contract, so I thought ok let's use them. Then it started. I got offered this really great deal only to be told that as fibre was not active in my area I could not get that deal but I can get this one. So I took it. That was in January last year. So about 3 months ago I see that all of a sudden we are using like 700 GB a day. I know right how on earth is that possible since we are not even home all day. So we started querying this only to find out that Vodacom won't send a technician out as it is not their policy to do so when it is there problem to fix. Then we phoned everyday and these are the responses I got. 1. Your services need to be restored. So switch off and unplug your router. We did this about 4 times a days. About 2 weeks after someone told us that our router is not configured to our line. So that took about 2 days to fix. I have had intermittent service from Vodacom and they say I am experiencing package loss. That is why so much data is being used. So after all said and done I still requested a technician to come out. About 3 months down the line and I am still waiting. So I decided to cancel with them. They told me someone will contact me in 24 to 48 hours. I am still waiting. My cancellation SR was log on the 7th now I hear that they will only cancel end of July. that you can even complain because you get absolutely NO SERVICE through this whole thing. I wish someone with intelligence could contact me. This is not even half of my issue that I have had. I am disgusted with Vodacom
