Some excellent staff. Services need improvement

I honestly would have rated 1 star as I experienced an issue with my electricity meter and had to wait over 12 hours for a resolution. The consultant would take my call and insist he would call me back and after hours of waiting I'd call myself for an update only to be told my issue had not been resolved. I spend most of the morning without electricity due to a malfunctioning meter. The only reason I rate 4 stars is because after numerous calls I eventually got through to a gentleman named Leslie who solved my issue within half an hour and remained patient and understanding despite my increased frustration at the situation. Outstanding service on his part. However the experience tells me not all staff receive the same level of training as i had one person make me wait half a day, overnight for an issue that took someone else less than 10mins to solve.
