NO COVERAGE AS PER THEIR WEBPAGE

I am so disappointed, last week I app**** for a contract for 3gig data with cell c and i looked on their webpage what the coverage is like and it shows 3g so I app**** for this package, It got delivered Friday and I have not been able to use it at all as threre is no coverage, Monday morning I phoned in to try and sort this out, Someone was going to phone me , I have spoken to 3 people from Monday, Ryan / Ayesha and then another gentleman and I was holding on for 24 min yesterday and still not getting any help, the service SUCKS - I need to change over to Vodacom surely there is a consumer right if you \buy"somehting and it doesnt work you should be able to get help"
