MetroFibre cancellation

I have honestly had the worst experience trying to cancel my current MetroFibre contract. I am moving between provinces and will therefore not need their services anymore however I have called for more than a week trying to cancel or freeze my contract only to be transferred from one person to the next without actually getting the help I need. I have sent emails to notify them that I need to cancel my contract however I have received no response. While their actual internet service has been great, their post installation service is appalling. I hope this can be resolved soon.
