contract cost more than prepaid

I have a business wireless sim line with telkom. after the companies bad income whe left the line unpaid and got a 8ta sim card. now if I buy airtime I get the amount of airtime I buy extra for free to call to any network and there is no rental fees. but with my contract they charge me rental and extras on standard monthly basis of more than R600. than I haven`t even used the phone. the only difference is the data is cheaper and included in the R600 but that only R100. and on a prepaid when my airtime is finished it is till you recharge, no reconection fees, but with a contract you pay for reconection.<br> <br> So to have a fixed line contract is more expensive than to have a prepaid and you only loose all the way, <br> what a *******.<br> I thought the contract customers who have been handled with more pride because its a fixed income.
