Thoroughly disgusted with airtime contract cancellation

For the past few months I have repeatedly and patiently tried to cancel my airtime contract with Edgars/RMCS since early January. I am so frustrated and disappointed with the customer service i have received. I would like to port to another network but this is being prevented. Yesterday when i called to inquire on the status of the cancellation i waited on hold and after a long while waiting, the call was cut. i didn't even manage to get through to talk to a consultant. I have exhausted all avenues of communication, it seems the only route to move forward is a legal route.
