I’ve been trying to leave feedback for a technician called Colin 87011. I had an on going problem and he’s the first person who didn’t try a quick fix then disappear. He followed up the problem and got it sorted not only that he has called back to make sure it was all still working. This person showed excellent customer service who went above and beyond. I feel he should get recognition for this but I can’t find anywhere to leave the feedback. Please can you tell me how I do this .
