Continues bad service

I phoned the call center on 14/09/2017 and explained that my vodacom sim does not want to connect to the internet, the gentleman told me to hold as he is checking on my sim card, then he told me to switch off my phone for 5min and the issue would be resolved. I did as he said and my sim could still not connect to the internet. Again I reported it, again the gentleman told me the same as the previous one, again I did as he said, and still my issue was not resolved. Now when I try phoning I have to hold on forever and a day before I get thru to a operator, which tells me the same as the previous ones, and which still doesn't resolve my problem.
