Cell C is the worst service provider

Cell C is the worst service provider ever when it comes to service and feedback. I upgraded a data contract from 2 gig to 20 gig via call centre. I have always been on top up contracts &ihave 3 contracts with cell c and all of them top-up. <br> a week after my 20 gig upgrade activated my data line was blocked and when I called in to ask why I cannot download my e-mails on my laptoand hap I was informed I had reached my limit of pro rata data of 2.6 gig for the month. I had used it in ONE WEEK which sounded impossible all my previous data contracts were between 1 & 2 gig I coped well on and now I had a much bigger data contract and it lasted only a WEEK. I inisted on cancelling the contract because that was impossible to have used up so much data in a week but was informed I couldn't cancel, I had to receive 1st account. <br> I went into branch in Montana to see what my account amount was. I was billed an extra amount I refused to pay as My data line was blocked. I was informed I requested extra data. I demanded a recording of upgrade and extra data request - still wait for 3 months &2 lines suspended for 3mnths .<br> I'm so frustrated and spoken to over 50 people no solution.
