Got a text from ‘Argos’ saying my delivery was confirmed, I haven’t ordered anything from argos and this number was the number in the texts for customer service, different from the argos official number. There were no links in the text message just a statement of delivery. It shows up with the real argos texts I’ve received but the form is slightly different.
