Seagate 1TB Slip eternal hard drive

Further to my earlier complaint about DionWired Woodmead Retail Park, response was that the supplier ie Pinnacle would not accept my interaction with them directly as the product was under warranty - if it was not then I could deal with them directly. Still not happy with #DionWired as they didn't come to the party with a solution as to how to protect the confidential information on the hard drive before handing over for repair.

Purchased a Seagate 1TB Slip eternal hard drive 7 August 2017 at DionWired Woodmead Retail Park. Used it 4 times successfully. Tried using 1 November 2017 not working. ? Did all necessary troubleshooting. Store advised will need to be repaired. Told them there is very confidential information stored and no way will I hand it over. Palesa got back to me to say that it needs to be processed through the store takes 3 weeks. Spoke to Admin Manager who said I could take it directly to the supplier but would find out first and call back. 3 hours later no contact!
