Bad service

I have phone the head office switchboard every day this week, having to wait for at least 15 minutes to get through, only to be cut off. <br> I have left messages for the Retention manager to call me back, without any results. <br> <br> I have for the past 2 days tried calling the call center to cancel my account, and 4 or 5 times after holding for 20+ minutes got cut off!<br> I find this the worst service that I have received in a long time, and is very disappointing!<br>
