Poor retention service

[Emily+Parle]

Our contract was up for renewal and as usual we called to discuss options. We were three times advised of better times to call to get a deal as there were none to be had at that time. 
Frustrated we then decided to try the cancellation route, to be advised by Sky to setup a new Wi-Fi contract with another provider first to avoid losing connectivity. 
Two weeks later we receive a text from Sky informing us a deal was available. After being passed from department to department we were quoted £2 less. 
What is even worse is that our account is frozen to show that we would need to pay £143 to continue the contract, and yet we cannot view what we would get for that.
So Sky my question is this - as a Platinum VIP member of 11 years plus - where within this retention process is the reward for loyalty that you publicise?

You're not addressing Sky here...

if you can't get a deal you're happy with then leave.  Anecdotally it seems hard to get a decent deal atm.
