For me, this promotion is a complete dud! I have been waiting over 5 days for the redeem text message - still nothing!
Also, I tried shouting an iced coffee to my sister. She tried to redeem it online and received the message "Oops, your details don't match".
I then tried to contact the promoter through their webpage. A contact box opened asking for my details but after completing it I found there was no way to submit it.
What a terrible way to run a promotion!
