Worst network ever

My fiance bought me a tab and it came with a cell c sim card, in my excitement i thought i could finally experience the reduced charges everyone goes through since on my phone i am on vodacom. Oh my word, its been a month of hell, besides whatsapp and Facebook that seem to be free, id be happy to pay for them if the network would work, everytime i want to use the internet, i need to restart my tab. Facebook takes forever to load and nothing else that requires network seems to work, i think the only people benefiting from cell c are the people on contract. I do appreciate the experience however because first thing tomorrow i am getting a vodacom sim card, i see why other networks charge so exorbitantly, its so the network works for everyone who is paying for it, either prepaid or contract. I really don't know how other cell c users survive on such a slow network, for me, its been the worst month ever no thanks cell c!!!!
