Not sure on that. I did email route. Does the text charge a premium? If so, I assume they are making there and assuming you purchased?
To be fair it does say to include email, address and name in the text (cheeky)
ive just sent a text 'gingerbread' to 84433 and got a reply back saying my free gingerbread house is on its way. but they dont have my address ???lol
I text my details but how do they know if I have purchased the items as no receipt evidence is needed via text?
