My experience with corsair is shockingly bad! I have a K70 5 months old and had an earlier issue with it but found a work around online so onto the fault with the F7 malfunction.
I login to support, fine so far want to submit a ticket for RMA and time after time after time the drop down part number (clearly printed on the box next to the serial number etc) won't allow me to submit the ticket...."Invalid Part Number??" So I think ok I'll submit an email to support....nope no email support....ah live chat!....after waiting hours and hours for them to come online it fails....I know I'll try phone support!....NO europe or UK phone numbers!!!
Shocking Corsair not good enough!
In the end I thought I'll just go back to Overclockers support and in under 3mins of taking my call I have printed off the RMA label and am boxing it all up ready to go back via OC to corsair I don't even have to pay for my parcel costs as OC have pickup points across the UK, this IS what customer support should be Corsair!
I am writing to the UK trading standards and get corsair to shake up its appalling customer service package in the UK.
