Huawei P7 uchoose flexi 200 Contract

Good Day<br> <br> I would like to take out the advertised contract special for the Huawei P7 on Uchoose flexi for 199pm. However my current contract on Cell c is only expiring on the 28th July and i do not want to lose my number. Cancellation of the contract charges are really exhorbitant.<br> <br> Please would it be possible for me to maybe take out the contract at a later stage. Or would it be possible for me to book a contract and then take it out later. I do believe the special is only till the 6th July. Would i be able to get an extension please?<br> <br> Can you advise what are my options as i really do want to take out the contract special but dont want to lose my number and i can only get out of my contract on the 28th July.<br> <br> Please help me out. I have tried emailing customer but could not get assistance as they require information that is not relevant.
