What was the increase for anyhows?
Long story short, I was with the network for about 10 years so when I was getting a new contract I asked for a better price on my bill.
I got the increase signed off and the call was recorded. A few months later the bill shot up and they denied that I should have ever gotten a reduction on my bill.
After fighting for a few days they told me I could listen to the recorded call but as I had made several in that period I would have to pay for each and they were around €10 each off the top of my head.
I eventually found proof of this deal and they said that in their T&C's that they're able to remove any promotion for no reason and with no notice at any time which is what they had done to me.
P.S. I checked with apple direct and as my phone was damaged after the other items failed it is not covered under warranty now.
