Not impressed with service after being loyal for years...

I have been a loyal client for years, now I have tried to contact them via email and telephonically where I was on hold for 32 mins and then had a customer service representative answer the phone, ask me for my details and then asked the reason I was calling and was very quick to tell me I needed to give a months notice (even though we pay for the month ahead and I would like to have it disconnected with immediate effect) and then proceeds to tell me she would like to talk to the cancellation department and puts me on hold again....at 35 mins I disconnected the call or I would probably still be on hold.
