Vodacom is a ****

I have been a Vodacom user for atleast 10 years and I have never really had issues until now.So I bought data for 7 days only to find that there was suddenly coverage issues.I reported them on day 1 to the Twitter account,because this was new and I was working with limited time.I was interrogated and led to believe that my problem will be solved with urgency. After 3 days,I started asking to be compensated because the problem wasn't fixed yet I had paid for their services. I was told to be patient and await feedback. It's officially day 7 and obviously ,no feedback,my money went down the drain.I contacted them and said I want my money back and now they are saying there's nothing they can do for me.I feel ****med!There is still no network coverage,we are still struggling to even make calls.They will give you a case number and never actually work on the case. They are a big **** and I'm utterly dissapointed!Why sell a service that isn't working then blame it on the customer?Obviously something is off,because Vodacom coverage was find in my area for years,so how is it my fault?
