Good news yesterday. After sticking to my guns and stating I would proceed with the matter via the small claims court, the retailer has sent a rocket up the backside of MSI and I received an email confirming they will be taking this laptop for return, they already arranged an RMA along with a full refund for the original sale price.
Very happy about this as you can imagine, just shows that patience and sticking to your rights works. Looking forward to buying A NON MSI BRANDED COMPUTER which does what it says on the tin!!
Good look anyone else, remember. In UK and you have 6 years to return that GT72 (or GT80) to the retailer, not MSI from the date of sale. If you do it you WILL get a refund in full.
Add GT80
