When did you sumbit your orriginal message to PM? I recall n the announcement they said they were working on emails from the 19th, so should be soon depending on your message date.
did did you include all the nessisary info?
old account name and number, ported number etc.
PM will adjust your PM billing cycle to the ported date so you will not pay for 2 services. are you using your old sim at the moment?
