I too fell for this -I sent the tablets back within the 14 day period -was unable to send via "Signed For" as it is a PO box address but I have got a proof of posting certificate and have taken a photo of the package with the relevant reference numbers on the OUTSIDE of the envelope, directly below the address (another sly condition!). Have just called my bank (Barclays) who are very aware of this company's antics-ordering a replacement card will not help as payment has been authorised against the account BUT if the payment is taken, it will be refunded when reported to your bank via the "Unsolicited Cancelled Order Payment" procedure. What a faff!!! I am usually soooooo careful! Hope this helps . (The other alternative is to close the bank account immediately).
