Daughter at uni got phone stolen but phone registered in my name, she reported it online, block wasn't put on for 24 hours meanwhile bill had been run up of £170, phoned 202 for help but useless. O2 were to send new sim, never appeared, went into local O2 shop after ten days, got new sim, posted it to daughter but staff advised not unblocking the number until she received sim in case it was stolen in post, now local staff can't get it unblocked. So fed up with lack of help from O2 and foreign call centre staff who I can't understand and dont understand me...poor poor service. Any advice?
