Exchange policy

I bought a shoe at Rage on 26/11/20 and I happen to misplace my receipt went in to branch for an exchange was told they can't do an exchange for me without a receipt, I work in retail every company can do an exchange without a receipt but apparently they changed their system so they can't help me . I phoned head office of which u spoke to customer care she was also very dumb and told me she doesn't know asked to speak to a manager Wendy who was very unhelpful either telling me abt their stupid system , I therefore asked did they consider customer needs with this upgrade cos it's clear to me Rage has the selfish approach to customers needs creating such system . Very disappointed and will never but at Rage after been buying for so many years for myself and kids. They inconsiderate and rude .
