Can't get refund for data overcharged

I am fed up with my Autopage CellC account! Since I changed to my new package, my account has been messed up. I have 1 gig data free per month. But they kept billing me for this free gig, and at 99c/Mb, they've been overcharging me with R1013.76 per month. After struggling to get a refund, they gave me small refunds twice, and it does not come close to covering the money they owe. I'm still trying to get my money back.<br> Anyway, their response about the data is that their computer system cannot apply the 1 free gig to my account, and the workaround will be to load 2gig and then charge me half price.<br> However, I do not get the option to add more data to my account. 2 gig is too little for me, and once depleted I need to pay the 99c/mb fee, and can't get the in-bundle rates of 15c/mb.<br> This is extremely unfair and expensive. If I was on prepaid I would be able to buy data bundles...<br> I'm now trying to see if I can cancel this stupid contract asap. I'm still trying to get info on what my cancellation fee will be, but to no avail, still waiting. & the longer I wait, the more money I'm losing...<br> I've been with Autopage for many years, but NEVER again. This company is hopeless!
