2 weeks requesting information to upgrade contract

I am due for an upgrade on my contract. I have phoned in every 2 days for over two weeks to speak to an agent to get information of a suitable contract to upgrade to. The calls get dropped frequently, promises to call back are never followed through, emails sent and references received are not followed through in the 24 hour response (or any response time) promised. <br> <br> Yesterday I spoke to Justice, the third person who has promised to get back to me regarding the upgrading of my contract, with no response. The longer the delay, the longer they can keep me on an expired contract, so no urgency on their part.<br> <br> This is the worst service I have experienced.
