Lack of communication

I have / had a loyalty card from PNA I would keep my points to purchase something I wanted . Well what surprise a few weeks back I presented my card for the cashier to swipe only to be told . We no longer use this card , I asked and the points on the card she shrugged her shoulders and said Emails were sent out regarding the discontinuation of the loyalty card , I never received one an email .

Last week I was in PNA and asked the cashier about the points - she said you had until the 1st March to redeem the points , there were notes at the entrance - so immediately confusion for me 1 person says email advice another says says signs in the store ? Why wasn’t this advised when i purchased from PNA , the last time ( this year )

I find this so disappointing and a company once thought was great I am now dubious about - anyone on the same position ???
