Orange PAYG Text Problem

Hi there,

Well.. I've been texting an o2 PAYG number for past few days, been working
fine but recently my text's havent been getting there (my phone says message
sent ok) but i've been recieving them OK.

Orange say its a technical problem which should be mended in 24-48 hours but
still not working! Is there anything I can do or just contact orange
(again)??

TIA

Tim.
