Unable to port back to the network

<p>Why are there no terms and conditions explaining that you cannot port back to me and you mobile? It's a little frustrating especially as I have decided to give the network a try again. I have read through the "my number" page on your site and there is no mention of this. I have now requested cancellation because I am unable to port. If I am unable to port back to you, at least let the client know in advance rather than let me go through this process and now I'm out of pocket. I hope there is cooling off period and I don't loose money. </p>
