RETENTION Nightmare

I have been trying to get through to retentions for the past month and a half to cancel a contract that ended. I called and keep getting cut off. One the agents has been trying to get me through as well but still no luck. I have gone into a branch only to be told that retentions are only available Monday to Friday. I have emailed Customer Service on 28 February and received a call back a week later only to be told that retentions will contact me. Till today nobody has contacted me. I have now also signed up for a home connector which has no signal for a week now. I really dont know why i am still paying for this poor service. I am now at a point where i want to cancel all 3 my contracts, but how am i gonna do that if i cant even cancel one. REALLY REALLY Bad service:(
