No Bucks

Good day, I recently complained about that I don't receive any ebucks when I purchase from Dischem, only to learn that when one swipes your Dischem Loyalty card, one does not earn ebucks. The problems that I don't owe any loyalty card from Dischem, further the the loyalty card used belonged to one of my friends. I wrote three emails, non of which was rep**** to, I feel that nor did FNB explained that if I swipe any other loyalty card one will not earn the points, further there was no explanation offered at any given stage at a till point, my question is why bother to ask if you have a ebucks card, bringing one under the impression that one will be earning points, when this is no the case? Further please could someone show the lady that worked with my complaint the last time where the reply button is, as she either lack the decency or the knowledge to reply to a complaint.
