Oh hi leaderstores. Shambles of a company! The problem isn't getting your money back. It's making sure you receive what you paid for so your tradesman can start work.
I just checked and it's "Concertino" not colours. https://www.diy.com/departments/concertino-natural-kolberg-oak-effect-laminate-flooring-1-48-m-pack/176232_BQ.prd
Why not pay with paypal? any problems and paypal can resolve?
In response to an above comment, Leader Floors hold lots of stock. This laminate was brought in bulk as it has the grey V-groove, normally not supplied to the UK, hence the low price. Still plenty left, next day delivery, but selling fast, snap it up while you can.
This is Swiss krono, not kono, or did you mean Swiss krono? I've never come across Colours. Will have to check it out next time I'm there.
