I bought an i7 laptop (for speed!) from Currys at the end of November. As this was very slow, kept crashing and freezing I was told to send it for repair through Knowhow. Suspiciously, perhaps, they informed me it was done within 3 days. When I got it back, the repair report claimed that the problem was "many and older versions of windows installed over the top of each other" (only Windows 10 was installed, ONCE), that they had tried to ring me (no such call, even checked missed calls etc.) and that they had checked and laptop worked ok. On top of all these false claims, the laptop showed no improvement at all. I tried to contact them using the online contact form: this does not work (tried using different browsers and computers for this), so I rang them. the operator spoke to "repairs" who claimed the same as earlier. Although she "logged" my complaint the only thing she offered was for me to take back the laptop to the store so that they can look at it again. She also suggested that they should "write down in big capitals exactly what the problem is" and suggested that they (the store staff) were responsible to check the repair was done properly. Could not comment, though, on the discrepancy of the claims on the report. So it looks like the laptop can keep going back and forth, clocking travel miles, without any repair and with them claiming anything they fancy: frustrating, appalling, disgraceful and all that: off to trading standards next...
