TL;DR Dyson discount code SAVE550 is not applying on cart despite being advertised in their promo, on product page in web & mobile, social media, & first page of Google results on 'SAVE550'. Dyson support put me on hold for 10 minutes to try to work out what to do, promised call back, hasn't happened. So it's an unobtainable deal.
Our Dyson V11 vacuum recently broke with the plastic trigger not working (a common fault - they break in half). I bought a replacement trigger & tried to repair it myself as it's out of warranty (purchased in 2019) however we couldn't get it to reliably work.
Knowing that lately I'd seen a discount for the Dyson V15s Detect Submarine Complete vacuum on socials and on their website at around the $1000 mark, I went back onto their site today to purchase one. The last few days it was straight discounted to $1099 but now they required you to add a code 'SAVE550' as advertised on their page to bring it down from $1649 to $1099.
You can see this for yourself - on the product page there's a pop-up at the bottom advertising it. Google 'SAVE550' you can see over a page of results and different promotional links that lead to the same product.
Problem is the SAVE550 code doesn't work at checkout. So I rang customer service and the customer support agent couldn't get it working either. And even though they can see the promotion themselves on their pages, they aren't given permission to process my order. So they've promised to call me back but it's been nearly 5 hours now and no response.
What a clusterfck. The only reason I have decided to stay with Dyson is I already had multi-tools and even though it breaks down after five years, when it works it was effective. But given these systems are designed to fail and even their website doesn't work, what's the point anymore?
EDIT: I just got a call to manually process the order on phone. So I guess there's that.
They probably added the promo banner before activating the code in the backend. Really stupid there is no error message as to what the issue is.
