poor poor service discovery vitality

yesterday my wife made her weekly points last week. she did the spin and then attempted to get a Dischem voucher, the system failed and froze. she communicated with Vitality over WhatssApp to inform them. she was sent a voucher directly via SMS. she was embarrassed at Dischem when the cashier tried 3 times to redeem the voucher, it failed every time. poor poor service. she communicated via Whatsaap to another agent to express displeasure. she was told that it was a platform error which would take few days to resolve. pathetic service.
