Unfortunately I hear this all too often when I go out to visit customers. They tell me that the electrician turned up hours after they had arranged, or in some cases not at all. This understandably leads to much frustration on the customers part and a lack of trust of electricians in general.
I have to admit that this kind of 'problem' is very common within the trade. PG Electrics however pride themselves on their punctuality and professional service, we understand that time is very valuable to you.
