CellC will disconect my number if I dont upgrade my contract

<p>I have had my CellC number for 10 years during the years I have changed my contract package everytime it is time for an upgrade, two years ago cell C let my change my phone contract to a data contract using a tablet that I also used as a phone, now that my contract is up for a renewal I wanted to get anouther phone and CellC said sorry this is a data line I can not change my contract tipe I need to wait till the contract has expired then I can get a phone. So I waited till it was up and now that I want a phone CellC says SORRY but your number can not go on pre-paid nor can I get a phone contract its either keep a data package or they disconnect my line! They want to force me to keep a data package!</p>
