So my 12 months of $50 sky had come to an end and knowing I had to give 28 days notice I rang them 30 days before. The 1st woman on the phone wasn't at all interested in keeping me at the $50 a month level, so I asked to be disconnected, at which point I was transferred to the disconnection team, the 2nd next woman was really surprised I wasn't willing to fork out $107 a month, so instead of disconnecting me she offered me another 3 months at the $50 rate. 

How many 3 months extensions can I get before they finally give up?
