I am so sorry
I think the mobile phone contract is the least of your worries, tbh
I absolutely hate the way the NRP can somehow become this God-like person who can do no wrong, particularly when they have fucked off and left the RP with all the shitwork and responsibilty
of course, they never say no and end up looking like the "cool, fun" parent, when in reality they are feckless non-parents
It makes me feel more and more that, in some cases, when couples split (barring abuse of course) that 50/50 residence should be bloody well enforced more so if the NRP never pay any maintenance anyway
I think Scape gives good advice
there isn't much you can really do, other than wait it out, stay pleasant and hope these teenagers find out that grass isn't greener, and actually having a bit of discipline and structure to your life is a bloody good thing
grr sorry, just feel a bit angry for you
