PATHETIC CUSTOMER SERVICE!!!

In April i got a SMS stating i have a R150 off promo discount. It was on the 25th of April 2025 when i was at the Makro in Woodmead, tried to redeem the code while i was in store so that i can use it and i got the actual code an hour later when i was already home. Last week, i called both the head office and call centre asking they resend the code as i changed phones and no longer have it. I was thrown from one pillar, to the next one, to the furthest post without any help. Is it that hard to resend a R150 off promo discount to a loyal customer?!?!?!?!?
