hey if the following scenero is this then you can keep your TP2 and TP without getting it blacklisted:
Say you call them, and tell them you lost your phone at a friends house, and you need a replacement, but you dont want them to turn off the lost phone because your going to try and look for it over the weekend.So your going to try calling it later on. In the meantime please send me my replacement phone- plus your exspecting a very very IMPORTANT phone call that has to be logged as a missed call or else it could cost you your job thats how important it is
then if i find it ill send it back thank you.......okay sir thankyou and bam your done... no blacklisted esn.
