Great IT support company. The WhizzIT team are professional, responsive and easy to work with. Any issues are dealt with quickly and they are never slow to pick up the phone. It is reassuring to know we can rely on them for our day to day IT support.
Great managed IT service provider. Thank you WhizzIT for a smooth migration from Google to Microsoft 365. We really appreciate how professional Billy is, and he is always on hand to help us over the phone. I would highly recommend WhizzIT.
They provide IT services for my 24 bed hotel, restaurant and newly refurbished sports bar and grill. Very responsive, knowledgeable and very reasonably priced. Special mention to Billy who never fails to pick up the phone.
