Thinking about cancelling! £125 best offer is insane

I've been a customer for 8 years, and now have all family phone contracts through Sky. my bill this month was over 140, went on to check and realised my contract had ended. spent FOUR hours getting the run around on a new contract and essentially they admitted that sky stream is a worse service than skyQ (what i currently have) but the best they could give me for standard package plus sky cinema & broadband was 125? Yet if i signed up as a new customer I'd be getting a bigger package and it would be 72? make it make sense!

I'm currently looking at other options because the prices seem insane to me
