I am not sure how you have achieved the rating you have. Are they all true I have to ask myself. You engineer what booked and arrived as planned. Did some work then offered to fit a splitter that was already attached. Already meaning the original was cut off by the engineer then offered to fit a splitter for £40 on top of the £70 charged. This is for a pensioner who he thought perhaps would be an easy touch. But how wrong. You have been given the opportunity to correct this but have declined. So as you know the next steps are proceedings. Trading standards to start with. Laws of trading.
