Yep. shoulda phoned those guys at retentions
I believe disconnecting via letter is the most insecure way of approaching it, it takes so long to get to the correct department. Simply phone them between 9 - 5 mon - fri, say what you want and they will disconnect providing you are within your contractual rights.
The people at the retentions department will be happy to help you out providing people dont expect them to bend rules. Its their job to try keep the customer, but if you put it straight to them, they wont go through any retention offers which are pretty nice, but if you are set on leaving, there's not much they can do
