Edwina Caviness-Bey | 9/21/25
"I was so glad to see our Technician arrive on time, cheerful, and cooperating with my mobility issues to get inside instead of just leaving when I couldn’t be at the door instantly like the HomeServe guy did! Our Service Dog liked him, so that was another good point in his favor. He quickly did an excellent job Of solving the problem, and he was very careful to pack my frozen foods in my cooler and would’ve put them back if I let him, but I wanted to re-organize. What a relief after all these weeks of being on the phone with LG, and worrying and wrestling with the freezer to get it open properly - weeks of malfunctioning over at last!!! Thank you, Gof!"
