Loyalty discount and dropping off after end of contract?

[Christo]

My contract with Tmobile ended a few months ago, I havent been checking my bills but it seems that my loyalty discount has been removed, in addition I have been charged for internet, where before I wasnt. I called them up and as my contract ended I am effectively out of contract so lost the benefits.

is this the norm? Is this even legal?
Now when/if I start a new contract Im going to have to start from scratch - its not exactly rewarding to log term customers is it..

Did you move to a rolling contract?

If so, then I would have thought upgrading would reinstate your benefits, at the cost of getting a worse deal than if you took out a new contract.
