@Christinepro Yes, if an account was suspended from non payment for 90 days, the account would have been closed and the number would have returned to the original carrier. Did she get this number new from PM? or did she ported it in from another provider?
What is the area code and the first 3 digits? i can look up for you to see if it is a number that belongs to PM/Telus. If it is, you can try to ask PM to assign you back after you activate a new line. If it is from another provider, you can only get the number back from that particular provider
HI @Christinepro If credit card wasn't changed, it could be Autopay failed in any of those months.
Please ask her to check the credit card and see from which month PM stopped charging (Maybe it was from the April 1st glitch). If it is just a bit over 90 days and Telus owns the number, maybe they can reassign it back to your friend.
