My mother was having problems with their Nokia 5.1 plus. When I looked at it, it seemed like it need a new cable. After she went to JB hifi, it seemed like the port was more bent, after the sales person handled it. I advised that a port is $14 or could do a return with Nokia or JB. Anyway, today they got onto a sale that Domayne is doing. They ended up with a two year contract with Optus at $65/month for a demo model Iphone 8. I am assuming they had to pay $300 more to buy the phone and use the $500 giftcard. I suggested cancelling and returning the phone as it seems like a ripoff. The phone was around $640 new with Vodafone in May. They mentioned that the phone costs $1200 still. I think they were confused with the Iphone XR. If the phone is a bit expensive that's one thing, but to sell a demo model as well seems unreasonable. I am assuming the total cost for the phone is $1560 + $300. The store also has heaps of bad reviews for pressuring sales tactics. Update: The phone was missing things like the headphones + the contract sim… anyway returned for an iPhone SE
Well that's important is that your relative is happy with the deal.
Stop looking at fixing other's.
