If you live in or around Perth, (UK), then these are the IT heroes for you! Our old iMac (mid 2011), was giving up the ghost because Microsoft Office software updates no longer support old iMac models and so we thought we could no longer access important business files and cherished family photos. But Dave at Qwerty sorted the bug. He came to the house, (on time), which was most convenient, and got the job done. Really pleasant and trustworthy company to deal with. We will be getting them back to transfer our old files across to new computer. (We don't trust sending computers away, to have this done, because the last time we did, all our data was lost thanks to a very well known high street electrical retailer beginning with C!)! So because of this, having independent experts, in the name of QWERTY coming to our house, gives us that extra peace of mind. Thank you Dave :)
