Dreadful customer service. The initial request was dealt with with a day and the offer of same day installation was made. The installation was OK but it went rapidly downhill from there. One PIR camera hasn't worked properly since installation and all that is offered is to change the batteries - 3 times so far. Advised an engineer would call between 3pm - 5pm. Not convinced this would happen I called on the day and was told the engineer would arrive between 6pm - 7pm. 7.15pm still no engineer and no contact. Absolutely hopeless and a couldn't care less attitude. Avoid this company at all costs.
