âArgos took money for an item I purchased online. Written on: 01/07/2015 by JasminHatch362 (1 review written). Argos took money for an item I purchased online. Then cancelled my order saying it was a mistake.Still sat there all weekend with my money in their account building interest though. can see why many reviews are so bad. Go in store no staff had to wait one hour for something I had already ordered. Parking charges, absolute dreadful. Sent pictures to customer service team they were not interested. I emailed to have managers email and all they do is refuse, all you get is an apology.
