No after sales service/bad service overall

I was offered a router end of July, which I accepted. After delivery I could not get this up and running as there were no instructions whatsoever, no booklet, no manual!!!! After I had to go to a Vodacom shop that assisted me I was connected.

Then a started to enquire as where/how I could see my data used, battery life etc etc....after 3 WEEKS AND 7 EMAILS I got a response. Now my wifi is not working AND I HOVE NO CLUE WHY!!! If I had a response on my first request I would have at least been able to check data and regulate use, and I can STILL not see how much data I have left - NOOOOOO just sell something to a customer and do not give a damn afterwards!!!! You are useless Vodacom!!!!!!
