Hi, I'm a Coles employee and as an employee benefit we are supposed to get 10% off all Optus phone plan fees until 31/03/19. Yet strangely all the plans found here https://offer.optus.com.au/exclusive-offer-19/ have been removed from the coles employee discount page, on the MyColes website page there is a deal for the Huawei Mate 20 Pro for $63.10 a month and when you click the link to sign up, it takes you to the discount page where there is no sign of that plan. Call me crazy, but I thought 10% off all plans actually meant 10% off ALL plans...
Remember that some plans are already heavily discounted they can't keep "discount stacking".
Your best bet, is to follow up the discount through your "My Coles" portal.
Those plan were on the discount page on Monday, but had been removed by Tuesday. I have spoken to someone from Coles Head office and they said that those plans shouldn't have been removed from the offer, especially The one for the Huawei mate 20 pro as it's an advertised offer on the mycoles page. They said they would be forwarding this issue on to the technical department and they would be contacting optus to find out why these offers were removed.
