Simple Sim Swop cant be done

I bought a Samsung S6 on Monday and I cant use it because Cell C is unwilling to do a sim swop for me due to a backlog in their back office. They dont want me to speak to anyone to escalate the query.<br> <br> I phoned in yesterday and three times today and all the agents just keep on promising that someone will phone me within an hour which never happens.<br> <br> I spoke to Thabiso and she promised that a manager will phone me shortly... did not happen as expected.<br> <br> I am stuck with this stupid network until April next year. Cant wait to get out of this contract. Is it not enough that we never have signal/network? <br> <br>
